Amstrad Cartridge Identification Device

2011-04-16T10:28:00Z

Nilquader: /* Clones */

[[Image:Inside GX4000 cart 1.jpg|frame|right|ACID protection chip within a cartridge (bottom)]]

The '''ACID''' (Amstrad Cartridge Identification Device) protection chip is used in the [[GX4000 cartridge|cartridges]] of the [[Plus]] series and the [[GX4000]] game console.

== Technical ==

The 16pin ACID chip (in the cartridge) is sending a serial data stream to the 160pin ASIC chip (in the computer). The data stream is generated by some shift/xor logic, and is also affected by the EPROM address/enable signals. If the data stream isn't correct, then the ASIC does scatter access to RAM, making the cartridge unusable.

;ACID reverse-engineered 13-16 February 2010 by nocash (Martin Korth)
;below is repeated on every CLK cycle...
CmpVal=13596h, XorVal=0c820h
if PinA0=1 then CmpVal=CmpVal XOR 0000ch, XorVal=XorVal XOR 00004h
if PinA1=1 then CmpVal=CmpVal XOR 06000h, XorVal=XorVal XOR 06000h
if PinA2=1 then CmpVal=CmpVal XOR 000c0h, XorVal=XorVal XOR 00080h
if PinA3=1 then CmpVal=CmpVal XOR 00030h, XorVal=XorVal XOR 00020h
if PinA4=1 then CmpVal=CmpVal XOR 18000h, XorVal=XorVal XOR 08000h
if PinA5=1 then CmpVal=CmpVal XOR 00003h, XorVal=XorVal XOR 00000h
if PinA6=1 then CmpVal=CmpVal XOR 00600h, XorVal=XorVal XOR 00000h
if PinA7=1 then CmpVal=CmpVal XOR 01800h, XorVal=XorVal XOR 00800h
if PinCE=0 AND (ShiftReg OR 100h)=CmpVal then ShiftReg=ShiftReg XOR XorVal
NewBit=ShiftRegBit0 XOR ShiftRegBit9 XOR ShiftRegBit12 XOR ShiftRegBit16
ShiftReg=(ShiftReg SHR 1) + (NewBit SHL 16)
Wait for falling edge on PinCLK
if PinCCLR=0 then ShiftReg=1FFFFh ;\done at falling CLK edge
PinSIN=ShiftRegBit0 ;/
;Mind that above is a software example - a hardware solution obviously
;wouldn't require CmpVal and XorVal registers - instead, hardware would
;directly deal with the PinAx (or NOT PinAx) signals.

Replacing or overwriting the EPROM in existing cartridges is easy, so the ACID doesn't prevent piracy or homebrew programming. However, it prevents commercial developers from producing unlicensed cartridges.

== Timings ==

Although the functionatlity of the ACID chip is known. The timings of the signals coming from the computer is still unknown (reverse-engineering was done on a ACID chip, without owning a CPC+/GX4000).
* CLK is known to be 4MHz, and SIN is known to be updated on falling edge of CLK, as seen on [[Media:ACID-SIN.jpg|this picture]].
* Judging from the ACID chip, /CCLR is checked on falling edge of CLK. However, juding from [[Media:ACID-CCLR.png| this picture]], /CCLR is ''changing'' on falling edge of CLK. If this is true (the picture resolution isn't perfect), then it's unclear how the ACID can interprete /CCLR in a stable way while it's changing. Possibly, it can't do that at all (ie. it might act unstable, and the CPC+ might need to retry sending /CCLR several times).
** '''WANTED:''' A picture showing CLK and /CCLR without ACID connected (at better resolution) would help!
** A picture showing CLK and /CCLR with ACID connected is [[Media:ACID Init by Grim.png|found here]].
* The /CE timing is still unknown, too. The ACID might check A0-A7 on raising or falling edge of /CE. Or, on raising or falling edge of CLK while /CE being LOW. Or at whatever other time.
** '''WANTED:''' A picture showing CLK and /CE would help!
** '''WANTED:''' Best also showing one or more of the A0-A7 signals.

The data stream is generated by some shift/xor logic, and is also affected by the EPROM address/enable signals. If the data stream isn't correct, then the ASIC does scatter access to RAM, making the cartridge unusable.

Nilquader: /* NC200 */

''The following text was copied in part from the [http://en.wikipedia.org/wiki/Amstrad_NC100 English Wikipedia article].''

[[Image:NC100.jpg|200px|thumb|Amstrad NC100]]

The '''Amstrad NC Series''' was a series of A4-sized, portable [[Z80|Z80]]-based computers, released by [[Amstrad]] in 1992-1993. All models featured 64 or 128 KB of RAM, the [[Protext]] word processor, various organiser-like facilities (diary, address book and time manager), a simple calculator, and a version of [[BBC Basic]].

The screen of the first two models (NC100 and NC150) was small, eight rows by 80 columns, and not backlit, but this let the NC100/150 run for up to 20 hours on four standard AA cell batteries. There was an RS232 serial port, a parallel port for connecting a printer, and a PC card socket, by means of which the computer's memory could be expanded up to 1 MB.

==Design==
The NC100 was designed to be a portable computer which was simple to use. That was the brief given by Sir Alan Sugar (then chairman of Amstrad) to his design staff. The NC100 project was internally referred to as Alan's "Baby" and Alan Sugar himself tested the machine for usability during the design phase. The specifications for the computer were not considered important - as long as it could serve its purpose.

The simple to use features of the NC100 come from the software which is included on the internal ROM chip. The Word processor and other applications have been written with a computer novice in mind - although experienced users can find and use a large array of more complicated features.

Alan Sugar actually wrote the first chapter of the NC100's user manual in order to show that even he could use it.

The design also included terminal emulation and XMODEM file transfer software which enabled the NC100 to communicate through dial-up analogue modems. UK tech journalist Sue Schofield used one to upload a review of the NC100 directly into the online filing computer of the Independent newspaper in 1993. The review was written on the machine, and transferred from it over a 300 baud modem.

==Hardware==

===NC100===
The NC100 was the first model of the Amstrad NC Series.

===NC150===
The NC150 was only available in Italy and france; Its case had the same design as the NC100, but it included the additional Software from the NC200 (Three Tetris-like games and a spreadsheet)

</gallery>

===NC200===
An upgraded version, the ''NC200'', appeared in late 1993, featuring a 3.5" floppy disk drive able to read/write MS-DOS-formatted double density disks, 128 KB RAM, some extra software - most notably a spreadsheet and three Tetris-like games - and a larger, backlit screen. However, this change required much greater power use, using 5 C cell batteries. The disk drive could only be used at near full-charge, which meant that it could only be used a few hours after putting in new batteries. However, the laptop could function for considerably longer than this without using the disk drive. The backlight can be manually toggled off to save power by pressing the Control and Caps Lock keys at the same time.

The Notepad comes with various software included on the ROM chip. The included software can be started at any time by pressing the ''Function'' key and one of the colored keys or letter keys simultaneously. These programs are included on the NC:
* Word Processor: A full featured port of Protext, including Mail Merge and spellchecker. (YELLOW-RED)
* Calculator: A very basic Calculator. Supports only basic arithmetic operations. (YELLOW-GREEN)
* Diary/Clock/Address Book: A simple calendar, adress book and world clock application. (YELLOW-BLUE)
* BBC Basic: BASIC interpreter with graphics and sound capabilities. Includes a two-pass Z80 assembler. (YELLOW-B)
* Serial Terminal: A (VT52 compatible) terminal program with XModem file transfer function. (YELLOW-S)
* Spreadsheet: (NC150/NC200 only) A version of 'The Cracker' spreadsheet ported to the NC. (YELLOW-WHITE)
* Blockade/Super Blockade/Trikade: (NC150/NC200 only) Three very similar Tetris-like games. (YELLOW-G)

===Serial Terminal===

NC100:

Press FUNCTION+S to enter Serial terminal. You can press MENU to change the settings.
Here characters that are received will be shown immediatly.

If you want to transfer a file, the best method is to use XMODEM. First you will

NLQ401

Nilquader: Added german NLQ401 user manual

The [[NLQ401]] is a Near Letter Quality printer from [[Schneider]], for use with German Schneider CPC computers. The '''SFT401''' tractor feed add-on was sold separately. Both NLQ401 and SFT401 were advertised as official Schneider expansions on the back of the german CPC6128 users manual.

== General Specifications ==

For (detailed) general information about Amstrad/Scheider printers, see:
{{AmstradPrinterLinks}}

== Hardware Notes ==

* The NLQ401 PCB can be optionally fitted with RS232 interface (25pin DSUB connector, and 75188/75189 voltage converters, this might also require a different firmware version).
* As seen on the photo, the board contains a [[uPD7810/uPD7811|uPD7811G]] processor, but its internal ROM is disabled via MODE0/MODE1 pins, so it does act more like a ROM-less uPD7810. According to the NLQ401 service manual either uPD7810 or uPD7811 can be used.
* The 16K EPROM is mapped to address 0000h..3FFFh. The MODE0/MODE1 pins are wired so that external memory uses only 14bit addresses (the upper 2bit of Port F are used as I/O signals, rather than as address bits)

== Reviews ==

* [[CPC Schneider International]], March 1985, page 24 (german) (this review contains some misleading info; among others claiming that it can print in 11 different character heights, as well as claiming that it'd support "user defined" "8bit" characters - which probably refers to the 7-pin graphics mode)

== Manuals ==

* [[Media:UPD78C11A Datasheet.pdf|uPD78C11A Datasheet]] (CMOS version of uPD7811, this datasheet version includes some info fragments on MODE0/MODE1 pins)

== Related Printers ==

The label, saying '''Centronics Data Computer Corp., Model No. 3101''', at the bottom of the NLQ401 printer reveals that the hardware wasn't produced by Schneider themselves. Nearly identical hardware was also distributed by other companies, like the '''Brother M1009'''.

Reportedly, the Schneider NLQ 401 is same as '''Centronics GLP 500''' and '''Brother M1009''' (but, see below for extra info concerning missing near-letter quality support on Brother M1009).

The NLQ 401 does also resemble the Commodore MPS-803 (at least externally).

=== Centronics GLP 500 ===

=== Commodore MPS-803 ===

[[File:Commodore MPS-803 dark with tractor.jpg|150px|right]]
Commodore printer, apparently from the same manufacturer, and probably containing more or less the same hardware. Known differences are: MPS-803 uses a CBM-style serial port (no centronics port). And control codes and character set in BIOS may differ from the Amstrad version, too. [[:File:Commodore MPS-803 dark boxed.jpg|(other picture)]]

The MPS-803 uses the same 9-pin head as the NLQ401, but reportedly it has only 8-pins installed, more confusingly, the MPS-803 uses only 7-pins for both Text and Graphics printing (producing a similar picture as the older MPS-801/[[DMP1]]).

* [[Media:Commodore MPS-803 Printer Users Guide.pdf|Commodore MPS-803 Printer Users Guide.pdf]]
 

=== Brother M1009 ===

[[File:Brother M1009.jpg|150px|right]]

Info from Michael Wessel:
:I was very happy when I could acquire a brand new, very inexpensive 9-pin dot matrix printer for only 200,- DM. The '''Brother M1009''' was a discontinued model. The only difference to the official 'CPC printer' which was sold by [[Schneider]], the [[NLQ401]], was a different case color, different label, and a software Eprom which enabled the NLQ 401 to print in Near Letter Quality which was something the M1009 couldn't do.

 

=== Robotron 6313 ===

[[File:Robotron.jpg|150px|right]]

The east-german [[Robotron 6313]] consists of different hardware, but it supports a [[NLQ401]] software compatible mode which can be activated via DIP switches.

NC Series

2010-09-24T12:30:01Z

Nilquader: /* NC100 */

''The following text was copied in part from the [http://en.wikipedia.org/wiki/Amstrad_NC100 English Wikipedia article].''

[[Image:NC100.jpg|200px|thumb|Amstrad NC100]]

The '''Amstrad NC Series''' was a series of A4-sized, portable [[Z80|Z80]]-based computers, released by [[Amstrad]] in 1992-1993. All models featured 64 or 128 KB of RAM, the [[Protext]] word processor, various organiser-like facilities (diary, address book and time manager), a simple calculator, and a version of [[BBC Basic]].

The screen of the first two models (NC100 and NC150) was small, eight rows by 80 columns, and not backlit, but this let the NC100/150 run for up to 20 hours on four standard AA cell batteries. There was an RS232 serial port, a parallel port for connecting a printer, and a PC card socket, by means of which the computer's memory could be expanded up to 1 MB.

==Design==
The NC100 was designed to be a portable computer which was simple to use. That was the brief given by Sir Alan Sugar (then chairman of Amstrad) to his design staff. The NC100 project was internally referred to as Alan's "Baby" and Alan Sugar himself tested the machine for usability during the design phase. The specifications for the computer were not considered important - as long as it could serve its purpose.

The simple to use features of the NC100 come from the software which is included on the internal ROM chip. The Word processor and other applications have been written with a computer novice in mind - although experienced users can find and use a large array of more complicated features.

Alan Sugar actually wrote the first chapter of the NC100's user manual in order to show that even he could use it.

The design also included terminal emulation and XMODEM file transfer software which enabled the NC100 to communicate through dial-up analogue modems. UK tech journalist Sue Schofield used one to upload a review of the NC100 directly into the online filing computer of the Independent newspaper in 1993. The review was written on the machine, and transferred from it over a 300 baud modem.

==Hardware==

===NC100===
The NC100 was the first model of the Amstrad NC Series.

</gallery>

===NC200===
An upgraded version, the ''NC200'', appeared in late 1993, featuring a 3.5" floppy disk drive able to read/write MS-DOS-formatted double density disks, 128 KB RAM, some extra software - most notably a spreadsheet and three Tetris-like games - and a larger, backlit screen. However, this change required much greater power use, using 5 C cell batteries. The disk drive could only be used at near full-charge, which meant that it could only be used a few hours after putting in new batteries. However, the laptop could function for considerably longer than this without using the disk drive. The backlight can be manually toggled off to save power by pressing the Control and Caps Lock keys at the same time.

===Serial Terminal===

NC100:

Press FUNCTION+S to enter Serial terminal. You can press MENU to change the settings.
Here characters that are received will be shown immediatly.

If you want to transfer a file, the best method is to use XMODEM. First you will
need to create a dummy document. (Press FUNCTION + Left Arrow, then Left Arrow, enter
name of doc, and then ESC to quit).

Now if you go to view documents, you can press MENU. From here you can choose
.... and do a xmodem receive document.

NC200:

Press FUNCTION+S to enter Serial terminal. From here you can press MENU, and choose
to do a xmodem receive or send or to setup the terminal. If you press RETURN instead of
MENU, you will enter the terminal like the NC100.

===XMODEM transfer===

NC100:

1. Enter wordprocessor.
2. Start a new document
3. Quit wordprocessor
4. Go to list documents.
5. Press MENU key
6. Here you can navigate the menu to find "XMODEM receive document".
7. Start XMODEM send on PC.

NC200:

1. Enter serial/terminal program.
2. Press MENU
3. Press R (for XMODEM receive)
4. Start XMODEM send on PC.

=== Third-party software for the NC Series ===
* ZCN: CP/M 2.2 compatible operating system. Requires at least a 256K PCMCIA Memory Card. [http://www.ibiblio.org/zcn/]

== The NC and relatives ==

The NC series has a remarkable resemblance to the Nakajima series of electronic typewriters!

<gallery caption="NC and Relatives">
Image:Ncandrelatives.jpg|The NC's and Nakajimas

== A Surgical Guide To The Amstrad Notepad Computer ==
This page is based on Hans-Jürgen Böhling's "surgical guide to the Amstrad NC". The original document is avaliabe here [http://home.arcor.de/h.boehling/nc100.htm] (author's website) or here [[Media:sg-nc100.zip]] (local copy)

=== Amstrad Notepad Computer - What is it? ===

The model NC100 is about DIN A4 size with a LCD 8 lines * 80 characters
screen, nearly full size keyboard, a PCMCIA memory card slot on the right
hand side and four coloured keys. The Notepads have standard Centronics
parallel port (DB-25 pin famale connector) and RS232 (DB 9 pin male)
serial port. The system has drivers for 9 and 24 pin dot matrix, Canon
inkjet and Laserjet printers. The serial connector support 300, 1200,
2400, 4800, or 9600 bps. As power supply the NC100 use 4 * AA sice
batteries or an AC adapter. As backup battery ther is also a CR2032 3 Volt
lithium cell.

The model NC150 (it seems) is retailing only in Italy and Fance. It has
512K bytes firmware ROM and 128K RAM. The extra 256K bytes ROM contains a
spreadsheet and the arcade game 'BLOCKADE' (similar to TETRIS).

The model NC200 include the additional features of the NC150 but also a
720K MS-DOS compatible 3.5 inch floppy disk drive and a 16 lines by 80
characters screen witch had to be fold up like a laptop.

</pre>

=== How to get the Firmware Number? ===

When you are in the main Menu (text editor, calculater, calender) push the
secret-button and the system-settings menu appears, the version number
will be shown in the first line of the sceen. I have a german NC100 and the
firmware number is v1.06.

=== PCMCIA Memory Cards ===

A battery buffered PCMCIA SRAM-Memory Card will preserve you from data loss
even if your Notepad crashes and increases the available memory. It also
allows you to create a file with BBC-BASIC bigger than 1024 bytes. This is
because BBC-BASIC allocates all available memory on startup except 1024
bytes. The maximum size to use with the NC100 is up to 1M byte.

=== How to open the NC100? ===

Before disassembling the Notepad you should save all your data! Then put
the Notepad on the table face down. Remove the four AA size batteries, then
unscrew the five screws (one under the battery cover). In the drawing below
they are marked with a "*"-sign. One screw fixes the cover of the firmware
EPROM.Place the Notepad the right way up and lift off the upper part of the
case. Be careful, because the display is still connected to the main-board
via a folio-flat-cable and so is the speaker! Don't be nervous, the cables
can be simply pulled out of their sockets. Now you can separate the covers.

[[File:NC100_HowToOpen.png]]

=== What is inside? ===

Inside the NC100 is a SMD layout. I have a german NC100 and the circuit board is
labeled Amstrad plc 4500-001P-1, NA999-32142, manual marked C (A-H) and
1 (1-8). All IC's are SMD apart from IC303 which is on the backside of the
NC100 (behind the firmware EPROM cover). On the drawing below I have
labeled all ICs, but you can find it on the layout also!

On my NC100 the IC304 is layouted as an SO 32 (32 pin). I belief you can
put some bigger RAM-chip in the circuit, but there is nothing about that in
the electronic diagram! There is only that the NC100 can control a 43256
RAM-chips. By the type of the RAM-chip there had to be set some different
connections and use IC310:

256Kb, 512Kb, and 1024Kb sizes.
The flash memory cards are not suitable for the NC-100. These have a
control register that must be written to before any read or write can take
place. Data transfers are then be done in sector chunks.

NC Series

2010-09-23T17:11:16Z

Nilquader:

''The following text was copied in part from the [http://en.wikipedia.org/wiki/Amstrad_NC100 English Wikipedia article].''

[[Image:NC100.jpg|200px|thumb|Amstrad NC100]]

The '''Amstrad NC Series''' was a series of A4-sized, portable [[Z80|Z80]]-based computers, released by [[Amstrad]] in 1992-1993. All models featured 64 or 128 KB of RAM, the [[Protext]] word processor, various organiser-like facilities (diary, address book and time manager), a simple calculator, and a version of [[BBC Basic]].

The screen of the first two models (NC100 and NC150) was small, eight rows by 80 columns, and not backlit, but this let the NC100/150 run for up to 20 hours on four standard AA cell batteries. There was an RS232 serial port, a parallel port for connecting a printer, and a PC card socket, by means of which the computer's memory could be expanded up to 1 MB.

==Design==
The NC100 was designed to be a portable computer which was simple to use. That was the brief given by Sir Alan Sugar (then chairman of Amstrad) to his design staff. The NC100 project was internally referred to as Alan's "Baby" and Alan Sugar himself tested the machine for usability during the design phase. The specifications for the computer were not considered important - as long as it could serve its purpose.

The simple to use features of the NC100 come from the software which is included on the internal ROM chip. The Word processor and other applications have been written with a computer novice in mind - although experienced users can find and use a large array of more complicated features.

Alan Sugar actually wrote the first chapter of the NC100's user manual in order to show that even he could use it.

The design also included terminal emulation and XMODEM file transfer software which enabled the NC100 to communicate through dial-up analogue modems. UK tech journalist Sue Schofield used one to upload a review of the NC100 directly into the online filing computer of the Independent newspaper in 1993. The review was written on the machine, and transferred from it over a 300 baud modem.

===NC200===
An upgraded version, the ''NC200'', appeared in late 1993, featuring a 3.5" floppy disk drive able to read/write MS-DOS-formatted double density disks, 128 KB RAM, some extra software - most notably a spreadsheet and three Tetris-like games - and a larger, backlit screen. However, this change required much greater power use, using 5 C cell batteries. The disk drive could only be used at near full-charge, which meant that it could only be used a few hours after putting in new batteries. However, the laptop could function for considerably longer than this without using the disk drive. The backlight can be manually toggled off to save power by pressing the Control and Caps Lock keys at the same time.

===Serial Terminal===

NC100:

Press FUNCTION+S to enter Serial terminal. You can press MENU to change the settings.
Here characters that are received will be shown immediatly.

If you want to transfer a file, the best method is to use XMODEM. First you will
need to create a dummy document. (Press FUNCTION + Left Arrow, then Left Arrow, enter
name of doc, and then ESC to quit).

Now if you go to view documents, you can press MENU. From here you can choose
.... and do a xmodem receive document.

NC200:

Press FUNCTION+S to enter Serial terminal. From here you can press MENU, and choose
to do a xmodem receive or send or to setup the terminal. If you press RETURN instead of
MENU, you will enter the terminal like the NC100.

===XMODEM transfer===

NC100:

1. Enter wordprocessor.
2. Start a new document
3. Quit wordprocessor
4. Go to list documents.
5. Press MENU key
6. Here you can navigate the menu to find "XMODEM receive document".
7. Start XMODEM send on PC.

NC200:

1. Enter serial/terminal program.
2. Press MENU
3. Press R (for XMODEM receive)
4. Start XMODEM send on PC.

=== Third-party software for the NC Series ===
* ZCN: CP/M 2.2 compatible operating system. Requires at least a 256K PCMCIA Memory Card. [http://www.ibiblio.org/zcn/]

== The NC and relatives ==

The NC series has a remarkable resemblance to the Nakajima series of electronic typewriters!

<gallery caption="NC and Relatives">
Image:Ncandrelatives.jpg|The NC's and Nakajimas
Image:Nakajima ES210 System s1.jpg|Closeup of Nakajima ES-210
</gallery>

These computers appear to use the same hardware as the NC100, except a NEC V20 (8086 compatible CPU) is used in place of the Z80.

A surgical guide to the Amstrad NC

2010-09-23T17:04:05Z

Nilquader: /* What is inside? */

== A Surgical Guide To The Amstrad Notepad Computer ==
This page is based on Hans-Jürgen Böhling's "surgical guide to the Amstrad NC". The original document is avaliabe here [http://home.arcor.de/h.boehling/nc100.htm] (author's website) or here [[Media:sg-nc100.zip]] (local copy)

=== Amstrad Notepad Computer - What is it? ===

The model NC100 is about DIN A4 size with a LCD 8 lines * 80 characters
screen, nearly full size keyboard, a PCMCIA memory card slot on the right
hand side and four coloured keys. The Notepads have standard Centronics
parallel port (DB-25 pin famale connector) and RS232 (DB 9 pin male)
serial port. The system has drivers for 9 and 24 pin dot matrix, Canon
inkjet and Laserjet printers. The serial connector support 300, 1200,
2400, 4800, or 9600 bps. As power supply the NC100 use 4 * AA sice
batteries or an AC adapter. As backup battery ther is also a CR2032 3 Volt
lithium cell.

The model NC150 (it seems) is retailing only in Italy and Fance. It has
512K bytes firmware ROM and 128K RAM. The extra 256K bytes ROM contains a
spreadsheet and the arcade game 'BLOCKADE' (similar to TETRIS).

The model NC200 include the additional features of the NC150 but also a
720K MS-DOS compatible 3.5 inch floppy disk drive and a 16 lines by 80
characters screen witch had to be fold up like a laptop.

</pre>

=== How to get the Firmware Number? ===

When you are in the main Menu (text editor, calculater, calender) push the
secret-button and the system-settings menu appears, the version number
will be shown in the first line of the sceen. I have a german NC100 and the
firmware number is v1.06.

=== PCMCIA Memory Cards ===

A battery buffered PCMCIA SRAM-Memory Card will preserve you from data loss
even if your Notepad crashes and increases the available memory. It also
allows you to create a file with BBC-BASIC bigger than 1024 bytes. This is
because BBC-BASIC allocates all available memory on startup except 1024
bytes. The maximum size to use with the NC100 is up to 1M byte.

=== How to open the NC100? ===

Before disassembling the Notepad you should save all your data! Then put
the Notepad on the table face down. Remove the four AA size batteries, then
unscrew the five screws (one under the battery cover). In the drawing below
they are marked with a "*"-sign. One screw fixes the cover of the firmware
EPROM.Place the Notepad the right way up and lift off the upper part of the
case. Be careful, because the display is still connected to the main-board
via a folio-flat-cable and so is the speaker! Don't be nervous, the cables
can be simply pulled out of their sockets. Now you can separate the covers.

[[File:NC100_HowToOpen.png]]

=== What is inside? ===

Inside the NC100 is a SMD layout. I have a german NC100 and the circuit board is
labeled Amstrad plc 4500-001P-1, NA999-32142, manual marked C (A-H) and
1 (1-8). All IC's are SMD apart from IC303 which is on the backside of the
NC100 (behind the firmware EPROM cover). On the drawing below I have
labeled all ICs, but you can find it on the layout also!

On my NC100 the IC304 is layouted as an SO 32 (32 pin). I belief you can
put some bigger RAM-chip in the circuit, but there is nothing about that in
the electronic diagram! There is only that the NC100 can control a 43256
RAM-chips. By the type of the RAM-chip there had to be set some different
connections and use IC310:

=== The PCMCIA card slot (IC306) ===

The NC-100 can use PCMCIA/JEIDA Memory Cards (PC-Cards) Type I, max. 1024K
(1M) byte static ram card, 5 Volts. You can bye them in 64Kb, 128Kb,
256Kb, 512Kb, and 1024Kb sizes.
The flash memory cards are not suitable for the NC-100. These have a
control register that must be written to before any read or write can take
place. Data transfers are then be done in sector chunks.

A surgical guide to the Amstrad NC

2010-09-23T14:39:55Z

Nilquader:

== A Surgical Guide To The Amstrad Notepad Computer ==
This page is based on Hans-Jürgen Böhling's "surgical guide to the Amstrad NC". The original document is avaliabe here [http://home.arcor.de/h.boehling/nc100.htm] (author's website) or here [[Media:sg-nc100.zip]] (local copy)

=== Amstrad Notepad Computer - What is it? ===

The model NC100 is about DIN A4 size with a LCD 8 lines * 80 characters
screen, nearly full size keyboard, a PCMCIA memory card slot on the right
hand side and four coloured keys. The Notepads have standard Centronics
parallel port (DB-25 pin famale connector) and RS232 (DB 9 pin male)
serial port. The system has drivers for 9 and 24 pin dot matrix, Canon
inkjet and Laserjet printers. The serial connector support 300, 1200,
2400, 4800, or 9600 bps. As power supply the NC100 use 4 * AA sice
batteries or an AC adapter. As backup battery ther is also a CR2032 3 Volt
lithium cell.

The model NC150 (it seems) is retailing only in Italy and Fance. It has
512K bytes firmware ROM and 128K RAM. The extra 256K bytes ROM contains a
spreadsheet and the arcade game 'BLOCKADE' (similar to TETRIS).

The model NC200 include the additional features of the NC150 but also a
720K MS-DOS compatible 3.5 inch floppy disk drive and a 16 lines by 80
characters screen witch had to be fold up like a laptop.

- Texteditor with mailmerge and spellchecker
- Address book
- Time manager (diary with alarm-clock)
- Calculator
- Terminal-programm (serial Tranfer with ASCII or XModem)
- BBC-BASIC with Assembler support
</pre>

=== How to get the Firmware Number? ===

When you are in the main Menu (text editor, calculater, calender) push the
secret-button and the system-settings menu appears, the version number
will be shown in the first line of the sceen. I have a german NC100 and the
firmware number is v1.06.

=== PCMCIA Memory Cards ===

A battery buffered PCMCIA SRAM-Memory Card will preserve you from data loss
even if your Notepad crashes and increases the available memory. It also
allows you to create a file with BBC-BASIC bigger than 1024 bytes. This is
because BBC-BASIC allocates all available memory on startup except 1024
bytes. The maximum size to use with the NC100 is up to 1M byte.

=== How to open the NC100? ===

Before disassembling the Notepad you should save all your data! Then put
the Notepad on the table face down. Remove the four AA size batteries, then
unscrew the five screws (one under the battery cover). In the drawing below
they are marked with a "*"-sign. One screw fixes the cover of the firmware
EPROM.Place the Notepad the right way up and lift off the upper part of the
case. Be careful, because the display is still connected to the main-board
via a folio-flat-cable and so is the speaker! Don't be nervous, the cables
can be simply pulled out of their sockets. Now you can separate the covers.

[[File:NC100_HowToOpen.png]]

=== What is inside? ===

Inside the NC100 is a SMD layout. I have a german NC100 and the plate is
labeled Amstrad plc 4500-001P-1, NA999-32142, manual marked C (A-H) and
1 (1-8). All IC's are SMD apart from IC303 which is on the backside of the
NC100 (behind the firmware EPROM cover). On the drawing below I have
labeled all IC's, but you can find it on the layout also!

On my NC100 the IC304 is layouted as an SO 32 (32 pin). I belief you can
put some bigger RAM-chip in the circuit, but there is nothing about that in
the electronic diagram! There is only that the NC100 can control a 43256
RAM-chips. By the type of the RAM-chip there had to be set some different
connections and use IC310:

=== The PCMCIA card slot (IC306) ===

The NC-100 can use PCMCIA/JEIDA Memory Cards (PC-Cards) Type I, max. 1024K
(1M) byte static ram card, 5 Volts. You can bye them in 64Kb, 128Kb,
256Kb, 512Kb, and 1024Kb sizes.
The flash memory cards are not suitable for the NC-100. These have a
control register that must be written to before any read or write can take
place. Data transfers are then be done in sector chunks.

A surgical guide to the Amstrad NC

Nilquader: /* A Surgical Guide To The Amstrad Notepad Computer */

== A Surgical Guide To The Amstrad Notepad Computer ==
This page is based on Hans-Jürgen Böhling's "surgical guide to the Amstrad NC". The original document is avaliabe here [http://home.arcor.de/h.boehling/nc100.htm] (author's website) or here [[Media:sg-nc100.zip]] (local copy)

=== Amstrad Notepad Computer - What is it? ===

The model NC100 is about DIN A4 size with a LCD 8 lines * 80 characters
screen, nearly full size keyboard, a PCMCIA memory card slot on the right
hand side and four coloured keys. The Notepads have standard Centronics
parallel port (DB-25 pin famale connector) and RS232 (DB 9 pin male)
serial port. The system has drivers for 9 and 24 pin dot matrix, Canon
inkjet and Laserjet printers. The serial connector support 300, 1200,
2400, 4800, or 9600 bps. As power supply the NC100 use 4 * AA sice
batteries or an AC adapter. As backup battery ther is also a CR2032 3 Volt
lithium cell.

The model NC150 (it seems) is retailing only in Italy and Fance. It has
512K bytes firmware ROM and 128K RAM. The extra 256K bytes ROM contains a
spreadsheet and the arcade game 'BLOCKADE' (similar to TETRIS).

The model NC200 include the additional features of the NC150 but also a
720K MS-DOS compatible 3.5 inch floppy disk drive and a 16 lines by 80
characters screen witch had to be fold up like a laptop.

</pre>

=== How to get the Firmware Number? ===

When you are in the main Menu (text editor, calculater, calender) push the
secret-button and the system-settings menu appears, the version number
will be shown in the first line of the sceen. I have a german NC100 and the
firmware number is v1.06.

=== PCMCIA Memory Cards ===

A battery buffered PCMCIA SRAM-Memory Card will preserve you from data loss
even if your Notepad crashes and increases the available memory. It also
allows you to create a file with BBC-BASIC bigger than 1024 bytes. This is
because BBC-BASIC allocates all available memory on startup except 1024
bytes. The maximum size to use with the NC100 is up to 1M byte.

=== How to open the NC100? ===

Before disassembling the Notepad you should save all your data! Then put
the Notepad on the table face down. Remove the four AA size batteries, then
unscrew the five screws (one under the battery cover). In the drawing below
they are marked with a "*"-sign. One screw fixes the cover of the firmware
EPROM.Place the Notepad the right way up and lift off the upper part of the
case. Be careful, because the display is still connected to the main-board
via a folio-flat-cable and so is the speaker! Don't be nervous, the cables
can be simply pulled out of their sockets. Now you can separate the covers.

[[File:NC100_HowToOpen.png]]

=== What is inside? ===

Inside the NC100 is a SMD layout. I have a german NC100 and the plate is
labeled Amstrad plc 4500-001P-1, NA999-32142, manual marked C (A-H) and
1 (1-8). All IC's are SMD apart from IC303 which is on the backside of the
NC100 (behind the firmware EPROM cover). On the drawing below I have
labeled all IC's, but you can find it on the layout also!

On my NC100 the IC304 is layouted as an SO 32 (32 pin). I belief you can
put some bigger RAM-chip in the circuit, but there is nothing about that in
the electronic diagram! There is only that the NC100 can control a 43256
RAM-chips. By the type of the RAM-chip there had to be set some different
connections and use IC310:

=== The PCMCIA card slot (IC306) ===

The NC-100 can use PCMCIA/JEIDA Memory Cards (PC-Cards) Type I, max. 1024K
(1M) byte static ram card, 5 Volts. You can bye them in 64Kb, 128Kb,
256Kb, 512Kb, and 1024Kb sizes.
The flash memory cards are not suitable for the NC-100. These have a
control register that must be written to before any read or write can take
place. Data transfers are then be done in sector chunks.

== A Surgical Guide To The Amstrad Notepad Computer ==
This page is based on Hans-Jürgen Böhling's "surgical guide to the Amstrad NC". The original document is avaliabe here [http://home.arcor.de/h.boehling/nc100.htm] (Authors website) or here [[Media:sg-nc100.zip]] (local copy)

=== Amstrad Notepad Computer - What is it? ===

The model NC100 is about DIN A4 size with a LCD 8 lines * 80 characters
screen, nearly full size keyboard, a PCMCIA memory card slot on the right
hand side and four coloured keys. The Notepads have standard Centronics
parallel port (DB-25 pin famale connector) and RS232 (DB 9 pin male)
serial port. The system has drivers for 9 and 24 pin dot matrix, Canon
inkjet and Laserjet printers. The serial connector support 300, 1200,
2400, 4800, or 9600 bps. As power supply the NC100 use 4 * AA sice
batteries or an AC adapter. As backup battery ther is also a CR2032 3 Volt
lithium cell.

The model NC150 (it seems) is retailing only in Italy and Fance. It has
512K bytes firmware ROM and 128K RAM. The extra 256K bytes ROM contains a
spreadsheet and the arcade game 'BLOCKADE' (similar to TETRIS).

The model NC200 include the additional features of the NC150 but also a
720K MS-DOS compatible 3.5 inch floppy disk drive and a 16 lines by 80
characters screen witch had to be fold up like a laptop.

</pre>

=== How to get the Firmware Number? ===

When you are in the main Menu (text editor, calculater, calender) push the
secret-button and the system-settings menu appears, the version number
will be shown in the first line of the sceen. I have a german NC100 and the
firmware number is v1.06.

=== PCMCIA Memory Cards ===

A battery buffered PCMCIA SRAM-Memory Card will preserve you from data loss
even if your Notepad crashes and increases the available memory. It also
allows you to create a file with BBC-BASIC bigger than 1024 bytes. This is
because BBC-BASIC allocates all available memory on startup except 1024
bytes. The maximum size to use with the NC100 is up to 1M byte.

=== How to open the NC100? ===

Before disassembling the Notepad you should save all your data! Then put
the Notepad on the table face down. Remove the four AA size batteries, then
unscrew the five screws (one under the battery cover). In the drawing below
they are marked with a "*"-sign. One screw fixes the cover of the firmware
EPROM.Place the Notepad the right way up and lift off the upper part of the
case. Be careful, because the display is still connected to the main-board
via a folio-flat-cable and so is the speaker! Don't be nervous, the cables
can be simply pulled out of their sockets. Now you can separate the covers.

[[File:NC100_HowToOpen.png]]

=== What is inside? ===

Inside the NC100 is a SMD layout. I have a german NC100 and the plate is
labeled Amstrad plc 4500-001P-1, NA999-32142, manual marked C (A-H) and
1 (1-8). All IC's are SMD apart from IC303 which is on the backside of the
NC100 (behind the firmware EPROM cover). On the drawing below I have
labeled all IC's, but you can find it on the layout also!

256Kb, 512Kb, and 1024Kb sizes.
The flash memory cards are not suitable for the NC-100. These have a
control register that must be written to before any read or write can take
place. Data transfers are then be done in sector chunks.

== A Surgical Guide To The Amstrad Notepad Computer ==
This page is based on Hans-Jürgen Böhling's "surgical guide to the Amstrad NC". The original document is avaliabe here: [http://home.arcor.de/h.boehling/nc100.htm]

=== Amstrad Notepad Computer - What is it? ===

The model NC100 is about DIN A4 size with a LCD 8 lines * 80 characters
screen, nearly full size keyboard, a PCMCIA memory card slot on the right
hand side and four coloured keys. The Notepads have standard Centronics
parallel port (DB-25 pin famale connector) and RS232 (DB 9 pin male)
serial port. The system has drivers for 9 and 24 pin dot matrix, Canon
inkjet and Laserjet printers. The serial connector support 300, 1200,
2400, 4800, or 9600 bps. As power supply the NC100 use 4 * AA sice
batteries or an AC adapter. As backup battery ther is also a CR2032 3 Volt
lithium cell.

The model NC150 (it seems) is retailing only in Italy and Fance. It has
512K bytes firmware ROM and 128K RAM. The extra 256K bytes ROM contains a
spreadsheet and the arcade game 'BLOCKADE' (similar to TETRIS).

The model NC200 include the additional features of the NC150 but also a
720K MS-DOS compatible 3.5 inch floppy disk drive and a 16 lines by 80
characters screen witch had to be fold up like a laptop.

</pre>

=== How to get the Firmware Number? ===

When you are in the main Menu (text editor, calculater, calender) push the
secret-button and the system-settings menu appears, the version number
will be shown in the first line of the sceen. I have a german NC100 and the
firmware number is v1.06.

=== PCMCIA Memory Cards ===

A battery buffered PCMCIA SRAM-Memory Card will preserve you from data loss
even if your Notepad crashes and increases the available memory. It also
allows you to create a file with BBC-BASIC bigger than 1024 bytes. This is
because BBC-BASIC allocates all available memory on startup except 1024
bytes. The maximum size to use with the NC100 is up to 1M byte.

=== How to open the NC100? ===

Before disassembling the Notepad you should save all your data! Then put
the Notepad on the table face down. Remove the four AA size batteries, then
unscrew the five screws (one under the battery cover). In the drawing below
they are marked with a "*"-sign. One screw fixes the cover of the firmware
EPROM.Place the Notepad the right way up and lift off the upper part of the
case. Be careful, because the display is still connected to the main-board
via a folio-flat-cable and so is the speaker! Don't be nervous, the cables
can be simply pulled out of their sockets. Now you can separate the covers.

[[File:NC100_HowToOpen.png]]

=== What is inside? ===

Inside the NC100 is a SMD layout. I have a german NC100 and the plate is
labeled Amstrad plc 4500-001P-1, NA999-32142, manual marked C (A-H) and
1 (1-8). All IC's are SMD apart from IC303 which is on the backside of the
NC100 (behind the firmware EPROM cover). On the drawing below I have
labeled all IC's, but you can find it on the layout also!

256Kb, 512Kb, and 1024Kb sizes.
The flash memory cards are not suitable for the NC-100. These have a
control register that must be written to before any read or write can take
place. Data transfers are then be done in sector chunks.

== A Surgical Guide To The Amstrad Notepad Computer ==
This page is based on Hans-Jürgen Böhling's "surgical guide to the Amstrad NC". The original document is avaliabe here: [http://home.arcor.de/h.boehling/nc100.htm]

=== Amstrad Notepad Computer - What is it? ===

The model NC100 is about DIN A4 size with a LCD 8 lines * 80 characters
screen, nearly full size keyboard, a PCMCIA memory card slot on the right
hand side and four coloured keys. The Notepads have standard Centronics
parallel port (DB-25 pin famale connector) and RS232 (DB 9 pin male)
serial port. The system has drivers for 9 and 24 pin dot matrix, Canon
inkjet and Laserjet printers. The serial connector support 300, 1200,
2400, 4800, or 9600 bps. As power supply the NC100 use 4 * AA sice
batteries or an AC adapter. As backup battery ther is also a CR2032 3 Volt
lithium cell.

The model NC150 (it seems) is retailing only in Italy and Fance. It has
512K bytes firmware ROM and 128K RAM. The extra 256K bytes ROM contains a
spreadsheet and the arcade game 'BLOCKADE' (similar to TETRIS).

The model NC200 include the additional features of the NC150 but also a
720K MS-DOS compatible 3.5 inch floppy disk drive and a 16 lines by 80
characters screen witch had to be fold up like a laptop.

</pre>

=== How to get the Firmware Number? ===

When you are in the main Menu (text editor, calculater, calender) push the
secret-button and the system-settings menu appears, the version number
will be shown in the first line of the sceen. I have a german NC100 and the
firmware number is v1.06.

=== PCMCIA Memory Cards ===

A battery buffered PCMCIA SRAM-Memory Card will preserve you from data loss
even if your Notepad crashes and increases the available memory. It also
allows you to create a file with BBC-BASIC bigger than 1024 bytes. This is
because BBC-BASIC allocates all available memory on startup except 1024
bytes. The maximum size to use with the NC100 is up to 1M byte.

=== How to open the NC100? ===

Before disassembling the Notepad you should save all your data! Then put
the Notepad on the table face down. Remove the four AA size batteries, then
unscrew the five screws (one under the battery cover). In the drawing below
they are marked with a "*"-sign. One screw fixes the cover of the firmware
EPROM.Place the Notepad the right way up and lift off the upper part of the
case. Be careful, because the display is still connected to the main-board
via a folio-flat-cable and so is the speaker! Don't be nervous, the cables
can be simply pulled out of their sockets. Now you can separate the covers.

What is inside?
---------------

Inside the NC100 is a SMD layout. I have a german NC100 and the plate is
labeled Amstrad plc 4500-001P-1, NA999-32142, manual marked C (A-H) and
1 (1-8). All IC's are SMD apart from IC303 which is on the backside of the
NC100 (behind the firmware EPROM cover). On the drawing below I have
labeled all IC's, but you can find it on the layout also!

On my NC100 the IC304 is layouted as an SO 32 (32 pin). I belief you can
put some bigger RAM-chip in the circuit, but there is nothing about that in
the electronic diagram! There is only that the NC100 can control a 43256
RAM-chips. By the type of the RAM-chip there had to be set some different
connections and use IC310:

The PCMCIA card slot (IC306)
--------------------

The NC-100 can use PCMCIA/JEIDA Memory Cards (PC-Cards) Type I, max. 1024K
(1M) byte static ram card, 5 Volts. You can bye them in 64Kb, 128Kb,
256Kb, 512Kb, and 1024Kb sizes.
The flash memory cards are not suitable for the NC-100. These have a
control register that must be written to before any read or write can take
place. Data transfers are then be done in sector chunks.

=== Amstrad Notepad Computer - What is it? ===

The model NC100 is about DIN A4 size with a LCD 8 lines * 80 characters
screen, nearly full size keyboard, a PCMCIA memory card slot on the right
hand side and four coloured keys. The Notepads have standard Centronics
parallel port (DB-25 pin famale connector) and RS232 (DB 9 pin male)
serial port. The system has drivers for 9 and 24 pin dot matrix, Canon
inkjet and Laserjet printers. The serial connector support 300, 1200,
2400, 4800, or 9600 bps. As power supply the NC100 use 4 * AA sice
batteries or an AC adapter. As backup battery ther is also a CR2032 3 Volt
lithium cell.

The model NC150 (it seems) is retailing only in Italy and Fance. It has
512K bytes firmware ROM and 128K RAM. The extra 256K bytes ROM contains a
spreadsheet and the arcade game 'BLOCKADE' (similar to TETRIS).

The model NC200 include the additional features of the NC150 but also a
720K MS-DOS compatible 3.5 inch floppy disk drive and a 16 lines by 80
characters screen witch had to be fold up like a laptop.

How to get the Firmware Number ?
--------------------------------

Wenn you are in the main Menu (text editor, calculater, calender) push the
secret-button and the system-settings menu appears, the version number
will be shown in the first line of the sceen. I have a german NC100 and the
firmware number is v1.06.

PCMCIA Memory Cards
-------------------

A battery buffered PCMCIA SRAM-Memory Card will preserve you from data loss
even if your Notepad crashes and increases the available memory. It also
allows you to create a file with BBC-BASIC bigger than 1024 bytes. This is
because BBC-BASIC allocates all available memory on startup except 1024
bytes. The maxinun sice to use with the NC100 is up to 1M byte.

-2-�
How to open the NC100 ?
-----------------------

Before disassembling the Notepad you should save all your data! Then put
the Notepad on the table face down. Remove the four AA size batteries, then
unscrew the five screws (one under the battery cover). In the drawing below
they are marked with a "*"-sign. One screw fixes the cover of the firmware
EPROM.Place the Notepad the right way up and lift off the upper part of the
case. Be careful, because the display is still connected to the main-board
via a folio-flat-cable and so is the speaker! Don't be nervous, the cables
can be simply pulled out of their sockets. Now you can separate the covers.

What is inside?
---------------

Inside the NC100 is a SMD layout. I have a german NC100 and the plate is
labeled Amstrad plc 4500-001P-1, NA999-32142, manual marked C (A-H) and
1 (1-8). All IC's are SMD apart from IC303 which is on the backside of the
NC100 (behind the firmware EPROM cover). On the drawing below I have
labeled all IC's, but you can find it on the layout also!

NC Series

2010-09-23T14:09:22Z

Nilquader: /* Technical */

''The following text was copied in part from the [http://en.wikipedia.org/wiki/Amstrad_NC100 English Wikipedia article].''

[[Image:NC100.jpg|200px|thumb|Amstrad NC100]]

The '''Amstrad NC Series''' was a series of A4-sized, portable [[Z80|Z80]]-based computers, released by [[Amstrad]] in 1992-1993. All models featured 64 or 128 KB of RAM, the [[Protext]] word processor, various organiser-like facilities (diary, address book and time manager), a simple calculator, and a version of [[BBC Basic]].

The screen of the first two models (NC100 and NC150) was small, eight rows by 80 columns, and not backlit, but this let the NC100/150 run for up to 20 hours on four standard AA cell batteries. There was an RS232 serial port, a parallel port for connecting a printer, and a PC card socket, by means of which the computer's memory could be expanded up to 1 MB.

==Design==
The NC100 was designed to be a portable computer which was simple to use. That was the brief given by Sir Alan Sugar (then chairman of Amstrad) to his design staff. The NC100 project was internally referred to as Alan's "Baby" and Alan Sugar himself tested the machine for usability during the design phase. The specifications for the computer were not considered important - as long as it could serve its purpose.

The simple to use features of the NC100 come from the software which is included on the internal ROM chip. The Word processor and other applications have been written with a computer novice in mind - although experienced users can find and use a large array of more complicated features.

Alan Sugar actually wrote the first chapter of the NC100's user manual in order to show that even he could use it.

The design also included terminal emulation and XMODEM file transfer software which enabled the NC100 to communicate through dial-up analogue modems. UK tech journalist Sue Schofield used one to upload a review of the NC100 directly into the online filing computer of the Independent newspaper in 1993. The review was written on the machine, and transferred from it over a 300 baud modem.

==Hardware==

===NC100===
The NC100 was the first model of the Amstrad NC Series.

===NC150===
The NC150 was only available in Italy and france; Its case had the same design as the NC100, but it included the additional Software from the NC200 (Three Tetris-like games and a spreadsheet)

</gallery>

===NC200===
An upgraded version, the ''NC200'', appeared in late 1993, featuring a 3.5" floppy disk drive able to read/write MS-DOS-formatted double density disks, 128 KB RAM, some extra software - most notably a spreadsheet and three Tetris-like games - and a larger, backlit screen. However, this change required much greater power use, using 5 C cell batteries. The disk drive could only be used at near full-charge, which meant that it could only be used a few hours after putting in new batteries. However, the laptop could function for considerably longer than this without using the disk drive. The backlight can be manually toggled off to save power by pressing the Control and Caps Lock keys at the same time.

==Software==
The Notepad comes with various software included on the ROM chip. The included software can be started at any time by pressing the ''Function'' key and one of the colored keys or letter keys simultaneously. These programs are included on the NC:
* Word Processor: A full featured port of Protext, including Mail Merge and spellchecker. (YELLOW-RED)
* Calculator: A very basic Calculator. Supports only basic arithmetic operations. (YELLOW-GREEN)
* Diary/Clock/Address Book: A simple calendar, adress book and world clock application. (YELLOW-BLUE)
* BBC Basic: BASIC interpreter with graphics and sound capabilities. Includes a two-pass Z80 assembler. (YELLOW-B)
* Serial Terminal: A (VT52 compatible) terminal program with XModem file transfer function. (YELLOW-S)
* Spreadsheet: (NC150/NC200 only) A version of 'The Cracker' spreadsheet ported to the NC. (YELLOW-WHITE)
* Blockade/Super Blockade/Trikade: (NC150/NC200 only) Three very similar Tetris-like games. (YELLOW-G)

===Serial Terminal===

NC100:

Press FUNCTION+S to enter Serial terminal. You can press MENU to change the settings.
Here characters that are received will be shown immediatly.

If you want to transfer a file, the best method is to use XMODEM. First you will
need to create a dummy document. (Press FUNCTION + Left Arrow, then Left Arrow, enter
name of doc, and then ESC to quit).

Now if you go to view documents, you can press MENU. From here you can choose
.... and do a xmodem receive document.

NC200:

Press FUNCTION+S to enter Serial terminal. From here you can press MENU, and choose
to do a xmodem receive or send or to setup the terminal. If you press RETURN instead of
MENU, you will enter the terminal like the NC100.

===XMODEM transfer===

NC100:

1. Enter wordprocessor.
2. Start a new document
3. Quit wordprocessor
4. Go to list documents.
5. Press MENU key
6. Here you can navigate the menu to find "XMODEM receive document".
7. Start XMODEM send on PC.

NC200:

1. Enter serial/terminal program.
2. Press MENU
3. Press R (for XMODEM receive)
4. Start XMODEM send on PC.

=== Third-party software for the NC Series ===
* ZCN: CP/M 2.2 compatible operating system. Requires at least a 256K PCMCIA Memory Card. [http://www.ibiblio.org/zcn/]

== The NC and relatives ==

The NC series has a remarkable resemblance to the Nakajima series of electronic typewriters!

<gallery caption="NC and Relatives">
Image:Ncandrelatives.jpg|The NC's and Nakajimas
Image:Nakajima ES210 System s1.jpg|Closeup of Nakajima ES-210
</gallery>

These computers appear to use the same hardware as the NC100, except a NEC V20 (8086 compatible CPU) is used in place of the Z80.

== Books ==
At least five book were published about the NC series!

Original NCIOSPEC.TXT follows:

The following notes describe the low level operation of the Amstrad Notepad
computers. They are intended for third party developers who want to program
the Notepad in machine code.

As always, I will try to help out if anyone has questions about this but I
cannot give an absolute guarantee to be able to provide support on the low
level operation of the machine.

It is our intention that these firmware routines and system variables should
be maintained in future issues of the software but we cannot give an absolute
guarantee about this.

bit 5 A13
bit 4 A12
bits 3-0 Not Used

On reset this is set to 0.

The display memory for the 8 line NC computers consists of a block of 4096
bytes where the first byte defines the state of the pixels in the top left
hand corner of the screen. A 1 bit set means the pixel is set to black. The
first byte controls the first 8 dots with bit 7 controlling the bit on the
left. The next 59 bytes complete the first raster line of 480 dots. The bytes
which define the second raster line start at byte 64 to make the hardware
simpler so bytes 60, 61, 62 and 63 are wasted. There are then another 64 bytes
(with the last 4 unused) which defines the second raster line and so on
straight down the screen. That is (all numbers decimal):

byte00 byte01 byte02 byte60 byte61 byte63
Bit Number 76543210 76543210 76543210 .. 76543210 76543210.. 76543210

Pixel Number 01234567 89012345 67890123 .. 23456789 wasted .. wasted
(read bottom 00000000 00111111 11112222 77777777
to top decimal) 00000000 00000000 00000000 44444444

....and so on for subsequent lines. (Second line = bytes 64..127 etc.)

Address = 10..13 Read/Write
Memory management control

10 controls 0000-3FFF
11 controls 4000-7FFF
12 controls 8000-BFFF
13 controls C000-FFFF

On reset all are set to 0.

For each address the byte written has the following meaning:

bit 7 together they select ROM, internal RAM, card RAM
bit 6 00b = ROM
01b = internal RAM
10b = card RAM

bits 5-0 determine address lines 19 to 14.

Therefore, 00 is the first 16K of ROM, 01 is the second 16K, etc.
40 is the first 16K of internal RAM, 41=second 16K, etc.
80 is the first 16K of card RAM, 81=second 16K, etc.

So, for example, if you want to switch the third 16K of internal RAM so the
processor sees it at 4000-7FFF you would output the value 42 to I/O address
11. 42 has bits 7,6 = 01b and bits 5-0 are 00010b which is the third 16K of
internal RAM.

Address = 20 Write only
Memory card wait state control

bit 7 = 1 for wait states, 0 for no wait

On reset this is set to 1. The bit should be set if the card RAM/ROM is
200nS or slower.

Address = 30 Write only
Baud rate etc.

bit 7 select card register 1=common, 0=attribute
bit 6 parallel interface Strobe signal
bit 5 Not Used
bit 4 uPD4711 line driver, 1=off, 0=on
bit 3 UART clock and reset, 1=off, 0=on

bits 2-0 set the baud rate as follows

000 = 150
001 = 300
010 = 600
011 = 1200
100 = 2400
101 = 4800
110 = 9600
111 = 19200

On reset all data is set to 1.

If programming the UART directly ensure that TxD clock is operating x16.

Address = 40 Write only
Parallel interface data

The byte written here is latched into the parallel port output register. To
print it you must then take the Strobe signal (I/O address 30 bit 6) low and
then high again. If the printer sends ACK this may generate an IRQ if the mask
bit is set in I/O address 60 - IRQ mask.

Address = 50..53 Write only
Sound channels period control

50 channel A period low
51 channel A period high

52 channel B period low
53 channel B period high

On reset all data is set to FF. The top bit in the high byte (51 and 53)
switches the resepective sound generator on or off - 1=off, 0=on.

The frequency generated is determined as:

Frequency = 1,000,000d
----------
data * 2 * 1.6276

So if the data word programmed into 50 and 51 was 7800 (ie 50=0, 51=78) then
the frequency generated would be:

freq = 1,000,000 = 1,000,000 = 1,000,000 = 10Hz
--------- --------- ---------
7800h * 2 * 1.6276 30720 * 2 * 1.6276 99,999.7

Address = 60 Write only
Interrupt request mask

bits 7-4 Not Used
bit 3 Key Scan interrupt (every 10mS)
bit 2 ACK from parallel interface
bit 1 Tx Ready from UART
bit 0 Rx Ready from UART

On reset all bits are 0. For each bit, 1=allow that interrupt source to
produce IRQs. 0 = interrupt source is masked.

Address = 70 Write only
Power off control
bits 7-1 Not Used
bit 0 1 = no effect, 0 = power off

On reset this is set to 1.

Address = 90 Read/Write
IRQ status

bits 7-4 Not Used
bit 3 Key scan
bit 2 ACK from parallel interface
bit 1 Tx Ready interrupt
bit 0 Rx Ready interrupt

When an interrupt occurs this port should be read to determine the source of
the interrupt. The bit will be set to 0 to identify the interrupting device.
The interrupt can then be cleared by writing 0 to that bit.

Address = A0 Read only
Memory card/battery status

bit 7 Memory card present 0 = yes, 1 = no
bit 6 Card write protected 1 = yes, 0 = no

bit 5 Input voltage = 1 if >= to 4 Volts
bit 4 Mem card battery. 0 = battery is low
bit 3 Alkaline batteries. 0 if >= 3.2 Volts
bit 2 Lithium battery. 0 if >= 2.7 Volts

bit 1 Parallel interface BUSY (0 if busy)
bit 0 Parallel interface ACK (1 if ACK)

Address = B0 - B9 Read only
Keyboard data

B0..B9 each key of the 64 on the keyboard
will set a bit in one of these bytes
while pressed.

The gate array scans the keyboard every 10mS and then generates an
interrupt. The program should then read these 10 I/O locations to
determine which key(s) is pushed. When I/O address B9 is read the
key scan interrupt is cleared automatically and the next scan cycle
will start from B0.

Address = C0 Read/Write
UART control/data

C0 UART data register
C1 UART status/control register

The UART is the NEC uPD71051. Programmers are advised to study the data
sheet for that chip for more information. The Serial interface requires
that the uPD4711 line driver chip be truned on by writing a 0 to bit 4 of
I/O address 30. While turned on power consumption increases so this should
only be done when necessary.

Address = D0 Read/Write
Real Time Clock chip (TM8521)

D0..DC Data
DD Control register
DE Control register (Write only)
DF Control register (Write only)

See data sheet of chip for more information.

NC100 operating system firmware

notes for external program writers

To get external programs executed on the Notepad you could either POKE
them into memory in BBC BASIC (or even use its built-in Z80 assembler)
and then CALL the entry point. However, this does have the drawback of
needing to transfer the code back to the machine each time it crashes
(as it inevitably will).

The simplest way to develop for the Notepad is to get a PCMCIA drive
for your PC and write a binary image direct to the card using that. If
this isn't possible then small programs (up to 16K) can be developed by
transferring the binary card image into the Notepad using Xmodem from
the PC. The use the "Make program card" feature in the File, transfer
menu to write that file onto a newly formatted PCMCIA RAM card.

In either case, to run the resultant code, you just press Function-X
(eXecute) and the first 16K page of the RAM card will be switched to
the Z80 memory map at C000..FFFF. A Check is made that location C200
holds the ASCII text "NC100PRG" and also that locations C210..C212
contains a long jump to C220. All being well, the Z80 starts executing
code at C210 so that, once you have control, you can take over
completely if you wish (driving all hardware functions directly). Most
people will probably want to cooperate with the in built firmware as it
provides most of the routines that one would require anyway.

The ASCII text "NC100PRG" must appear at C200h
program origin is C210h
program MUST start with jp C220h
the program name is at C213h, max 12 characters, zero terminated

org C200h
db "NC100PRG"
org c210h
jp start
db "PROGRAM NAME",0
org C220h
start

available workspace A000h to A3FFh (shared with other programs)
also A800h to AFFFh (this is overwritten if selectfile is called)
the program MUST handle yellow events :-
either exit when Stop is pressed
or check for yellow event with kmgetyellow and return if carry set

Serious developers may be interested in contacting Ranger Computers Ltd
on (+44) 604 589200 as they can produce a device that looks like RAM to
a PC but ends in a PCMCIA header plug that connects directly to the
Notepad's card slot and the "PC RAM" appears as card RAM to the Notepad.

The following sequence is a working(!) piece of code written for the
AVMACZ80 assembler on a PC, which, when assmembled produces a binary
file that can be programmed onto a PCMCIA card and executed. The
program just reads keys and prints them back until "Q" is pressed.

Notice that exit from the program is just by a RET back to the
operating system that called it:

;^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
; code is assembled with:
; AVMACZ80 TEST.ASM
;which produces a .OBJ file which is then linked to produce a .HEX file
;with the command
; AVLINK @TEST.LNK
;where TEST.LNK contains:
; TEST.HEX=TEST.OBJ -RUNSAT(Fred, 0C000h)
;finally the Intel .HEX file is converted to .BIN using a HEX2BIN converter
;The .BIN file is either written to the PCMCIA card using a PC based
;card drive or it can be Xmodemed across to the Notepad and written to
;the card using "Make program card". Finally, Function-X executes it.

In other assemblers you may not have "segments" and must use a direct
ORG to locate code at C000 but watch out for the resultant .HEX file
being padded out with 48K of "0"s from 0000 to BFFF!!

Alphabetic list of routine entry points

To use any one of these routines just load the registers as described in
the following and then call the relevant address. Although the running of the
routine may involve a different ROM bank being switched in, this mechanism
is invisble to the caller. So, for example, to print a capital A one might use:

general notes:
most routines return carry set if successful

================
heapalloc = B881
================
allocates a block of memory from the heap
ENTRY - DE = number of bytes to allocate
EXIT - HL = memory handle in range [1,63] if successful
HL = 0 if failed
Note: heapaddress must be used to get a pointer to the memory block
Unless the block is locked with heaplock, heapaddress must be
called each time the memory block is used. IT MAY HAVE MOVED!

===============
heapfree = B884
===============
frees a block of memory
ENTRY - DE = memory handle, returned by heapalloc or heaprealloc
EXIT - none (preserves HL,BC)
Note: the memory handle passed must be a valid handle returned by
heapalloc or heaprealloc. This is not validated.

===============
heaplock = B887
===============
locks or unlocks a memory block
ENTRY - DE = memory handle
BC = non zero - the block is locked. It will not be moved
until unlocked so fixed addresses can be used as
pointers into the block
BC = 0 - the block is unlocked

==================

==================
returns the largest block size that can be allocated
ENTRY - none
EXIT - HL = largest free block size in bytes

==================

==================
changes the size of an allocated memory block
ENTRY - DE = memory handle
BC = new size for memory block
EXIT HL = zero if failed to reallocate
The old block will not be freed but could have moved
HL = non-zero if successful
Note: if the block is being expanded, it must be assumed that the
base of the memory block will be moved (even if the block cannot
actually be expanded) so heapaddress must be called afterwards.
If the block is being contracted, the base will not move.

- BC = number of bytes read
- HL = address after last byte read
KNOWN BUG (1.00,1.01) - finblock does not set the file position
so repeated calls will always read from the start of the file
Workaround: call fseek after calling finblock to set the pointer

============

EXIT - c=1 if successful
c=0, A corrupt if end of file reached
A corrupt, other regs preserved

==============
frename = B8B1
==============
renames a file
ENTRY - HL = zero-terminated old filename
- DE = zero-terminated new filename
EXIT - c=1 if OK, c=0 if error (file not found)

============
fseek = B8B4
============

ENTRY - DE = file handle
- BC = offset from start of file
EXIT - c=1 if successful
c=0 if offset past end of file (pointer not changed)
KNOWN BUG (1.00,1.01) - leaves error messages enabled (fnoisy)
Workaround: call fquiet after fopenout if necessary

============
fsize = B8B7
============
finds size of file
ENTRY - HL = zero-terminated filename
EXIT - c=1 HL=size in bytes, if found
- c=0 if not found

==================
fsizehandle = B8BA
==================
finds size of an open file
ENTRY - DE = file handle
EXIT - HL=size in bytes

===============
tests whether end of file has been reached
ENTRY - DE=file handle
EXIT - c=1 if not eof, c=0 if eof

=================
selectfile = B8C3
=================
displays the file selector (clears the screen first)
shows all files and allows a selection to be made
using the cursor keys and RETURN
ENTRY - none

==================
kmgetyellow = B8D2
==================
ascertains whether a 'yellow event' is pending
(so called because the FUNCTION key is coloured yellow)
a yellow event occurs (i) when the user has pressed one of the
the FUNCTION+key combinations that cause an immediate context switch
(FN+red, FN+green, FN+blue, FN+menu)
or (ii) when the machine is powered up and (because the option to
preserve context has not been set) needs to return to the main menu

ENTRY - none
EXIT - c=1, BC=token if yellow event pending
An application should exit normally as quickly as possible
Any UNSAVED FILES should be SAVED AUTOMATICALLY!
- c=0, BC=0 if no yellow event pending

Note: each of the yellow event keys return the ESC token (2FCh)
An application should call kmgetyellow whenever an ESC is read,
this distinguishes between a yellow event and an ordinary ESC.

==================
kmsetyellow = B8D5
==================
sets up a yellow event. Specialised use only.
ENTRY - BC = a yellow event token
EXIT - none

=====================
lapcat_receive = B8D8

NC Series

2010-09-22T16:12:22Z

Nilquader: /* NC100 */ added more pictures and board scans

''The following text was copied in part from the [http://en.wikipedia.org/wiki/Amstrad_NC100 English Wikipedia article].''

[[Image:NC100.jpg|200px|thumb|Amstrad NC100]]

The '''Amstrad NC Series''' was a series of A4-sized, portable [[Z80|Z80]]-based computers, released by [[Amstrad]] in 1992-1993. All models featured 64 or 128 KB of RAM, the [[Protext]] word processor, various organiser-like facilities (diary, address book and time manager), a simple calculator, and a version of [[BBC Basic]].

The screen of the first two models (NC100 and NC150) was small, eight rows by 80 columns, and not backlit, but this let the NC100/150 run for up to 20 hours on four standard AA cell batteries. There was an RS232 serial port, a parallel port for connecting a printer, and a PC card socket, by means of which the computer's memory could be expanded up to 1 MB.

==Design==
The NC100 was designed to be a portable computer which was simple to use. That was the brief given by Sir Alan Sugar (then chairman of Amstrad) to his design staff. The NC100 project was internally referred to as Alan's "Baby" and Alan Sugar himself tested the machine for usability during the design phase. The specifications for the computer were not considered important - as long as it could serve its purpose.

The simple to use features of the NC100 come from the software which is included on the internal ROM chip. The Word processor and other applications have been written with a computer novice in mind - although experienced users can find and use a large array of more complicated features.

Alan Sugar actually wrote the first chapter of the NC100's user manual in order to show that even he could use it.

The design also included terminal emulation and XMODEM file transfer software which enabled the NC100 to communicate through dial-up analogue modems. UK tech journalist Sue Schofield used one to upload a review of the NC100 directly into the online filing computer of the Independent newspaper in 1993. The review was written on the machine, and transferred from it over a 300 baud modem.

==Hardware==

===NC100===
The NC100 was the first model of the Amstrad NC Series.

===NC150===
The NC150 was only available in Italy and france; Its case had the same design as the NC100, but it included the additional Software from the NC200 (Three Tetris-like games and a spreadsheet)

===NC200===
An upgraded version, the ''NC200'', appeared in late 1993, featuring a 3.5" floppy disk drive able to read/write MS-DOS-formatted double density disks, 128 KB RAM, some extra software - most notably a spreadsheet and three Tetris-like games - and a larger, backlit screen. However, this change required much greater power use, using 5 C cell batteries. The disk drive could only be used at near full-charge, which meant that it could only be used a few hours after putting in new batteries. However, the laptop could function for considerably longer than this without using the disk drive. The backlight can be manually toggled off to save power by pressing the Control and Caps Lock keys at the same time.

==Software==
The Notepad comes with various software included on the ROM chip. The included software can be started at any time by pressing the ''Function'' key and one of the colored keys or letter keys simultaneously. These programs are included on the NC:
* Word Processor: A full featured port of Protext, including Mail Merge and spellchecker. (YELLOW-RED)
* Calculator: A very basic Calculator. Supports only basic arithmetic operations. (YELLOW-GREEN)
* Diary/Clock/Address Book: A simple calendar, adress book and world clock application. (YELLOW-BLUE)
* BBC Basic: BASIC interpreter with graphics and sound capabilities. Includes a two-pass Z80 assembler. (YELLOW-B)
* Serial Terminal: A (VT52 compatible) terminal program with XModem file transfer function. (YELLOW-S)
* Spreadsheet: (NC150/NC200 only) A version of 'The Cracker' spreadsheet ported to the NC. (YELLOW-WHITE)
* Blockade/Super Blockade/Trikade: (NC150/NC200 only) Three very similar Tetris-like games. (YELLOW-G)

===Serial Terminal===

NC100:

Press FUNCTION+S to enter Serial terminal. You can press MENU to change the settings.
Here characters that are received will be shown immediatly.

If you want to transfer a file, the best method is to use XMODEM. First you will
need to create a dummy document. (Press FUNCTION + Left Arrow, then Left Arrow, enter
name of doc, and then ESC to quit).

Now if you go to view documents, you can press MENU. From here you can choose
.... and do a xmodem receive document.

NC200:

Press FUNCTION+S to enter Serial terminal. From here you can press MENU, and choose
to do a xmodem receive or send or to setup the terminal. If you press RETURN instead of
MENU, you will enter the terminal like the NC100.

===XMODEM transfer===

NC100:

1. Enter wordprocessor.
2. Start a new document
3. Quit wordprocessor
4. Go to list documents.
5. Press MENU key
6. Here you can navigate the menu to find "XMODEM receive document".
7. Start XMODEM send on PC.

NC200:

1. Enter serial/terminal program.
2. Press MENU
3. Press R (for XMODEM receive)
4. Start XMODEM send on PC.

=== Third-party software for the NC Series ===
* ZCN: CP/M 2.2 compatible operating system. Requires at least a 256K PCMCIA Memory Card. [http://www.ibiblio.org/zcn/]

== The NC and relatives ==

The NC series has a remarkable resemblance to the Nakajima series of electronic typewriters!

<gallery caption="NC and Relatives">

</gallery>

These computers appear to use the same hardware as the NC100, except a NEC V20 (8086 compatible CPU) is used in place of the Z80.

== Books ==
At least five book were published about the NC series!

To use a (PC/CPC Plus-style) DB-25 printer cable on a classic CPC, an adapter is needed. This adapter can be build using a female DB-25 socket and an edge connector (or a male Centronics plug for the german Schneider CPC). Using ribbon cable crimp connectors is the easiest way. Just connect each plug to the ribbon cable and pay attention that you always connect the red wire to pin 1 of the connector. Then cut pin 16 (which is the printer reset pin) using a sharp knife.
