[[Image:amssio.jpg|right|thumb|250px|The AMSSIO mounted inside a CPC464]]

The AMSSIO interface is a [[RS232]] interface by the dane, [[Martin Zacho]].
As opposed to other serial interfaces the AMSSIO is meant to be installed on top of the [[Z80]] CPU in the CPC. However the circuit can easily be built on a breadboard and connected to the expansion port as well.

AMSSIO exists in 3 different versions.

A new and improved version is the AMSSIO II.

== Description ==

AMSSIO is a RS-232 serial interface for the CPC464 (and 664/6128) and it exists in three different versions which all uses the MC6850 asyncronous communication interface adapter (ACIA) from Motorola.

* The first version was based on components from the scrap yard. But the MC14411 is a bit bulky and by now rather old and somewhat hard to find. The second and third version was an attempt to work around the MC14411.
* Version 2 uses a 4060 ripple counter as clock generator. But it can be tricky to make it operate at 2.5 MHz. This was the reason for version 3...
* The version 3 uses a 74LS393 to divide the 4 MHz CPU clock by 26 to obtain the 153 kHz for the serial clock (9600 * 16).

"I couldn't get the software to receive faster than 9600 :-( But it was at least 4 times faster than the tape transfer rate :-)."
All three versions are supposed to use the CPU socket in the CPC. The CPU socket on AMSSIO is meant to be a wire wrap socket. The CPU is removed from the CPC main board. AMSSIO is mounted in the empty socket and the CPU is placed in the 40 pin socket on the AMSSIO.

== Technical ==

=== AMSSIO (v1,v2,v3) ===
Connects between Z80 CPU and mainboard. I/O Ports for AMSSIO v1,v2,v3 are:

FBF0h AMSSIO Serial Interface [[6850 ACIA chip|MC6850]] Control/Status Register (R/W)
FBF1h AMSSIO Serial Interface [[6850 ACIA chip|MC6850]] Data Register (R/W)

For details on the MC6850 chip, see [[6850 ACIA chip]].

Observe that the baudrate CLK sources differ for v1,v2,v3. In v3 the CLK is fixed, v1/v2 have different jumper-selectable CLKs. And, the photo shows a different CLK crystal than the schematic. So, don't expect different AMSSIOs to be compatible with each other.

=== AMSSIO-II (v4) ===

AMSSIO-II is a newer version, using a 44pin 16C850CJ instead of the 24pin MC6850. Aside from the schematic (see below), there is no documentation or source code for AMSSIO-II. I/O base address can be FBE0h or FBF0h (jumper-selectable). Unlike the previous versions, this version also connects to the Z80's interrupt input.

The "PC" attached to the "16C850CJ" part number (labeled as "16C850CJPC" in schematic) is meant to say that the chip is wired to "PC Mode" (SEL, Pin 34 = GND). In the PC Mode, the chip tries to decode PC ISA bus addresses (COM1-4 = 3F8h,2F8h,3E8h,2E8h), some address lines are swapped, so the AMSSIO maps to FBE0h or FBF0h (selected by S1 input) whilst the chip "thinks" it is mapped to COM3/COM4 ISA bus addresses (3E8h/2E8h). ''Unclear: the jumper on S1 should change "A8" - but the schematic is wired as if "A4" changes - which would require a jumper on S2, not on S1 (?)''

* [[Media:XR16C850.pdf]] - 16C850 Datasheet

== Software ==

The software for AMSSIO can simulate a disk drive and a printer on a PC connected via RS-232. The software comes in two parts. The first part is for the CPC. It replaces relevant parts of the jump block, redirecting disc and printer access via RS-232. The second part is called CPCSHELL and runs on a PC under DOS or Linux. Part of the PC harddisk can be used as a giant CPC disk via this mechanism.

A spare PC can therefore be used as a method to add a cheap harddisk to the CPC. Although the software required on the CPC reduces compatibility somewhat it works for most well behaved applications and games that consist of a single binary (no special loader).

* '''PLEASE NOTE: The schematics and files have a few errors:'''
** MC6850 pin 7 (/IRQ output, in v1-v3) is connected to Vcc, but should be left unconnected.
** The signal marked 153.8MHz (in v3) is, of course, 153.8kHz (4MHz/13/2).
** The photo seems to show v1 and uses 1.8432MHz crystal, whilst schematic v1 uses 10MHz (?)
* Note: The Z80 CPU shown in schematic is your CPC's built-in CPU (mounted piggy-back on the AMSSIO cart)

Z80 STI RS232 interface

2010-05-10T17:33:16Z

Zigzac:

== Intro ==

This interface was originally described in the book "[[Maschinenspracheprogramme und Hardware-Erweiterungen für Schneider CPC's]]" written by [[Paul Bauriedl]], released by IDEA Verlag in 1987. Around mid-nineties, Tim Riemann has circulated the schematic as GIF in the internet.

The circuit is nearly indentical to the [[Schneider RS232 Interface]] from 1985, both circuits are using a [[Media:Mostek_3801_Data.pdf|Z80 STI]], both mapped to the same I/O port addresses. Both circuits seem to be driven by the 4MHz signal on the CPC's expansion port, so even the the timings should be 100% compatible. The only difference is that the DIY circuit uses more logic chips for decoding of the I/O port addresses (the extra chips are just more over-complicated, not actually better). Another difference, concerning the power supply, is that the Schneider circuit contains 2 diodes and 2 diodes for converting ~7V AC to +/-7V DC.

== How to build a RS232 - Interface for the CPC-Series! ==

=== Schematic and source code ===

First about the connection plan: You need a power supply that supports +9V,-9V and 5V. Connect all pins. You have to connect D0..D7 from the adressbus with the Z80 STI. You have to connect D0 with pin 21, D1 with pin 22, ..., D7 with pin 28. That's all.
Now you can plug in the interface in the CPC. Switch the power on. If the CPC doesn't work normal please switch the power off and you have to watch for faults in the connection of your interface :-(. If everything is ok then you have to copy the assembler code and do the next test.

Second part: How to program the interface. (The assembler code is saved in RS232.ASM)

Z80-STI: 50 to 19200 bps (5,6,7 or 8 bit, 1, 1 1/2, 2 stopbits, all parity flags) 24 registers, use 16 registers (direct) with F8E0-F8EF, the last 8 registers can be used indirect with a special register

== The meaning and the Addresses of the registers ==

=== Register 0 (Port F8E0h) Indirect Data ===
This register transfers data from and to a indirect register.

=== Register 1 (Port F8E1h) Handshake signals ===
This register transfers the data from and to the I/O port of the chip. If you use V24 you can request handshake signals from this port. In this interface the following bits have this meaning:
Bit 0: DTR (Data Terminal Ready)
Bit 1: RTS (Ready to Send)
Bit 2: CTS (Clear to Send)
Bit 3: DSR (Data Set Ready)
Bit 4-7: not used

=== Register 2-7 (Port F8E2h-F8E7h) Interrupt related ===
These registers are used by the interrupt handler. If you want to know
what you can do with this registers please write to Mostek for support.

=== Register 8 (Port F8E8h) Indirect Index ===
Bit 3-7 are used by the interrupt handler. With bit 0-2 you can choose the indirect register.

=== Register 9 (Port F8E9h) Timer Controls ===
Control register for timer A and B. You needn't to use the timer for a V24 interface.

=== Register 10 (Port F8EAh) Timer B ===
Timer B value

=== Register 11 (Port F8EBh) Timer A===
Timer A value

=== Register 12 (Port F8ECh) Mode Control ===
USART-register. Change the connect-parameters.
Bit 7 6 5 4 3 2 1 0
x x x x x x x 0
^ ^ ^ ^ ^ ^ ^
| | | | | | 1=even
| | | | | | 0=odd
| | | | | 1=Parity on
| | | | | 0=Parity off
| | | Startbit Stopbit Format
| | | 0 0 = 0 0 synchron
| | | 0 1 = 1 1 asynchron
| | | 1 0 = 1 1 1/2 asynchron
| | | 1 1 = 1 2 asynchron
| 0 0 = 8 Bit
| 0 1 = 7 Bit
| 1 0 = 6 Bit
| 1 1 = 5 Bit
please always set on 0

=== Register 13 (Port F8EDh) Rx Status ===
Receiver status. You need only the following bits:
Bit 0: Receiver-Enable, set to 1 if receiving is possible.
Bit 1: Memory full "1" or not "0". (If 8 Bits are
received then the interface send memory full).

=== Register 14 (Port F8EEh) Tx Status ===
Sending status. Again you need only two bits:
Bit 0: Sending-Enable, must set to "1" if sending is allowed.
Bit 7: Memory full "1" or not "0". This bit can
be used to ask if a word is send or not.

=== Register 15 (Port F8EFh) Rx/Tx Data ===
This is the send and receive register. Here you can get a word or send a word.

== Indirect registers (Choose them with register 8) ==

register 0: Not used.

register 1: Data for Timer D.

register 2: Data for Timer C.

register 3: Not used.

register 4: Not used.

register 5: Not used.

register 6: I/O-Port (receive or send). High means sending, low receiving.

register 7: Used for Timer C and D. Reset with "1".

For more exact informations please write to Mostek and ask for support for the Z80-STI. You also can look at the assembler code.

== About the assembler code ==

The program RS232.ASM installs 2 new BASIC commands (|FORMAT, |RECORD, |SEND).
Here you can read the description about this new commands:

'''|FORMAT''', number of bps, number of stop-bits, data bits, parity on/off, parity even/odd

Number of bps:

0 = 50 bps
1 = 75 bps
2 = 110 bps
3 = 150 bps
4 = 300 bps
5 = 600 bps
6 = 1200 bps
7 = 2400 bps

Number of stop bits: 1 = 1 stop bit
0 = 2 stop bit

Data bits: 0 = 7 data bits
1 = 8 data bits

Parity: 1 = even
0 = odd

Parity: 1 = on
0 = off

Normally, you use 8N1 for connection with BBS's you can initialise this with
|FORMAT, number of bps, 1, 1, 0, 1.

'''|RECORD''', @a$
The incoming chars will be read in a string. Control codes will be send to the
string, too, because sometimes you need it for binary transmissions.

'''|SEND''', @a$
The string is send until it ends, except you press ESC. The program will not
send CR or LF, so you can use this for binary transmission.

== Used components: ==

* 1x [[Media:Mostek_3801_Data.pdf|Z80-STI (MK3801-4)]]
* 1x SN75189 - RS232 to TTL level shifter
* 1x SN75188 - TTL to RS232 level shifter
* 1x 74LS30 - Single 8-input NAND gate
* 1x 74LS138 - 1-of-8 inverting decoder/demultiplexer
* 1x 74LS20 - Dual 4-input NAND gates
* 1x 74LS04 - Hex Inverters
* 1x 74LS32 - Quad 2-input OR gates
* 1x 25pin SUB-D connector (male)
* 1x connector for the [[Connector:Expansion_port|expansion port]]
Note: The 74LS20, 74LS04, 74LS32 are the smaller logic symbols in the schematic.

Note 2: The 74LS138 splits the address space to four regions (which is total nonsense), the 74LS20 is then merging them back to a single region (which is undoing that nonsense). There seems to be no real reason for doing that - except maybe to avoid legal copyright problems (claiming something like "no this isn't a unlicensed remake of Schneider's schematic, our schematic is doing total nonsense, it's has absolutely nothing to do with Schneider's hardware").

'''|FORMAT''', number of bps, number of stop-bits, data bits, parity on/off, parity even/odd

Number of bps:

0 = 50 bps
1 = 75 bps
2 = 110 bps
3 = 150 bps
4 = 300 bps
5 = 600 bps
6 = 1200 bps
7 = 2400 bps

Number of stop bits: 1 = 1 stop bit
0 = 2 stop bit

Data bits: 0 = 7 data bits
1 = 8 data bits

Parity: 1 = even
0 = odd

Parity: 1 = on
0 = off

Normally, you use 8N1 for connection with BBS's you can initialise this with
|FORMAT, number of bps, 1, 1, 0, 1.

'''|RECORD''', @a$
The incoming chars will be read in a string. Control codes will be send to the
string, too, because sometimes you need it for binary transmissions.

'''|SEND''', @a$
The string is send until it ends, except you press ESC. The program will not
send CR or LF, so you can use this for binary transmission.

== Used components: ==

* 1x Z80-STI (MK3801-4)
* 1x SN75189 - RS232 to TTL level shifter
* 1x SN75188 - TTL to RS232 level shifter
* 1x 74LS30 - Single 8-input NAND gate
* 1x 74LS138 - 1-of-8 inverting decoder/demultiplexer
* 1x 74LS20 - Dual 4-input NAND gates
* 1x 74LS04 - Hex Inverters
* 1x 74LS32 - Quad 2-input OR gates
* 1x 25pin SUB-D connector (male)
* 1x connector for the [[Connector:Expansion_port|expansion port]]
Note: The 74LS20, 74LS04, 74LS32 are the smaller logic symbols in the schematic.

Note 2: The 74LS138 splits the address space to four regions (which is total nonsense), the 74LS20 is then merging them back to a single region (which is undoing that nonsense). There seems to be no real reason for doing that - except maybe to avoid legal copyright problems (claiming something like "no this isn't a unlicensed remake of Schneider's schematic, our schematic is doing total nonsense, it's has absolutely nothing to do with Schneider's hardware").

Schneider RS232 Interface

2010-05-10T17:29:19Z

Zigzac: /* Datasheet (not Missing) */

RS232 Interface for the CPC by [[Schneider]]. Schneider is the german distributor for Amstrad CPC hardware (however, this
interface seems to be Schneider's own invention, not an Amstrad product).

Note: The uncommon shape of the housing dates back to a Schneider BTX modul (which was being intended to be plugged into Schneider Television Sets). Apparently Schneider produced too many housings, and re-used them for the RS232 interface. Actually, a RS232 interface is very much the same as a BTX interface (the actual BTX modem must be rented separately from Deutsche Bundespost), so even the PCB may be (almost/exactly?) the same for both devices.

Before spanish laws led to the 72K fake and to the spanish keyboard, normal english CPCs might have been sold in spain - unknown if this has really happened - and if so, if they had the spanish ''Ordenador Personal en Color'' text on them...?

[[File:NoPicture.png|100px|left]]
* '''Spanish CPC 464/664/6128 without Ñ key''' Pre-472

= Character Set ROMs =

Together with the customized keyboards, the BIOS ROMs character sets were changed accordingly. The new characters are potentially useful for home-use, but may result in compatibility problems when importing/exporting software to/from other countries - or even within the same country (the new character sets were invented around 1986, so older french/spanish/danish CPCs didn't support the new symbols).

'''Default Symbols'''
The english BIOSes are also used in german models. Until around 1986 (when localized keyboards/BIOSes were invented), the english BIOSes were also used in spanish/french/danish CPCs.
 

== French ==

* chr(7Bh) "é" instead "{"
* chr(7Ch) "ù" instead "|"
* chr(7Dh) "è" instead "}"
* chr(82h) "°" instead umlaut symbol
Changed chr(7Ch) means RSX commands become ùCPM instead |CPM.
The keyboard itself does have both "ù" and "|" keys, but, the default BIOS/BASIC tables do map "ù" to both of them.
 

== Spanish ==
[[File:Charset spanish gray.gif|left]]
'''Spanish BIOSes'''
* 40037 Spanish 464/472
* 40038 Spanish 6128

'''Special Symbols'''
* chr(81h) "Ñ" instead "´"
* chr(83h) "Pt" instead "£"
* chr(8Bh) "ñ" instead "±"
The changed pound/peseta currency symbol may result in some confusion, since the actual exchange rate is unlikely to be 1:1.
 

== Danish ==

* chr(7Bh) "æ" instead "{"
* chr(7Ch) "ø" instead "|"
* chr(7Dh) "å" instead "}"
Similar as in french, RSX commands like "|CPM" become "øCPM".
 

= Notes =

* According to soft968 the official language variants are: Spanish, French and Danish. And, presumably, English was official, too.

* Although french/danish charsets don't support "|", even newer user manuals (like french cpc+ manual from 1990) still refer to RSX commands as "|CPM" and describe to press shift+"@" to get the "|".

[[File:WalgenbachAmstrad CPC464 grey Large.jpg|200px|left]]
* '''Amstrad CPC 464 with new logo and grey keys'''
* Normally grey keys were found only on german Schneider models, not on Amstrad 464.
* Possibly this is a late german model (made after the Schneider/Amstrad partnership ended)...?
* Though [http://www.homecomputer.de/pages/f_info.html?Amstrad_CPC464_grey.html this link] says it's "most common" in UK...?
* Btw. better "non-diagonal" picture would be nice.

''Amstrad Ordinateur Personnel Couleur''

Early french models had french plaques on the keyboard and tape/disc drive, but still had english QWERTY keyboards. The french AZERTY keyboards were invented around 1986.

''Schneider Colour Personal Computer''

German CPCs have normal english keyboards. The keyboards (or case) is only different in so far that it is labeled Schneider instead Amstrad, and the 664/6128 have german colour tables on the disc drive. And, the keys are gray, unlike the more colorful Amstrad ones.

[[File:Schneider464keyboard.jpg|200px|left]]
* '''German CPC 464''' (Schneider)
* With Schneider logo and grey text on tape drive.
* Grey control keys (unlike multi-colored ones found in other countries).
 

[[File:NoPicture.png|100px|left]]
* '''German CPC 464 (Amstrad) (should exist?)'''
* Produced after the Amstrad-Schneider partnership ended in 1988. Now having an Amstrad logo on keyboard, ''unknown if/how such late german CPCs differed from english CPCs - they might have grey control keys, or german text on tape drive...?''
 

[[File:German Schneider CPC664 keyb Gryzor.jpg|200px|left]]

* With Schneider logo and german colour table on disc drive.
* In this version, the text layout resembles that of the english 6128.
 

[[File:Schneider6128keyboard.jpg|200px|left]]
* '''German CPC 6128''' (Schneider) (other variant)

* '''German CPC 6128''' (Amstrad)
* Produced after the Amstrad-Schneider partnership ended in 1988. Now having an Amstrad logo on keyboard, but still having a german colour table on the disk drive.
 

== Spanish ==

''Amstrad Ordenador Personal en Color''

Before spanish laws led to the 72K fake and to the spanish keyboard, normal english CPCs might have been sold in spain - unknown if this has really happened - and if so, if they had the spanish ''Ordenador Personal en Color'' text on them...?

[[File:NoPicture.png|100px|left]]
* '''Spanish CPC 464/664/6128 without Ñ key''' Pre-472
* According to info from spain: All spanish CPCs (at least the 6128) did have spanish plaques, even before the Ñ key was invented. So, these model(s) should exist. Photos would be welcome!
* EDIT: According to newer info - it now seems they DON'T exist.
 

[[File:CPC 472 es.jpg|200px|left]]

== Other ==

[[File:Awa CPC464.jpg|150px|left]]
* '''Australian AWA models''' were shipped with normal english keyboards (with the standard Amstrad logo above the ESC key), the only difference is that [[LK-selectable Brand Names|LK1 and LK2]] are shortened on the mainboard, so the BIOS displays [[Awa]] instead of Amstrad in the boot message.
 

* '''Greek CPCs''' are standard english Amstrad models, without any customized logos or keyboard.
* '''Other countries''' ... ''please add some info on Austria, Belgium, USA, etc.''

[[File:Kcc top.jpg|150px|left]]
* '''KC Compact''' [[KC Compact|(more info)]]

[[File:CPC664 D-o-S membrane unrotated.jpg|380px|left]]
* '''CPC 664 Keyboard Circuit'''
* Single foil (with 19pin connector).
* Connections are closed when the key touches the contacts on the foil.
* Not actually a membrane keyboard (since the foil doesn't move), seems to work more like the old PCB keyboard.

* '''CPC 6128 Keyboard Circuit'''
* Two membrane foils (with 2x10pin connector)
* Connections are closed when the key presses the two foils against each other.

* '''CPC Plus Keyboard Circuit'''
* Two membrane foils (with 2x10pin connector)
* Same as in CPC 6128, but with connection cable at rear side.
 

[[File:Kcc open.jpg|380px|left]]
* '''KC Compact Keyboard Circuit'''
* PCB with real mechanic switches, possibly the most robust CPC keyboard, even more robust than the early 464 PCB keyboards. Only downside is that it lacks the F5..F9 keys.
 

'''Keyboard / Case Dimensions'''
* CPC 464 - 580x170x70 mm (according to 464 service manual)
* CPC 664 - 580x170x70 mm (according to 664 service manual)
* CPC 6128 - 510x170x48 mm (according to 6128 service manual)
* CPC Plus - 398x297x46 mm (according to 464+/6128+ service manual)
* GX 4000 - 250x184x44 mm (according to 464+/6128+ service manual)
* KC Compact - 399x218x43/54 mm (serviceanleitung) or 388x218x43/54 mm (gerätebeschreibung) (?) or 3388x218x43 mm (!) (www.robotrontechnik.de and www.ddr-rechentechnik.de) (???)
* Aleste 520EX - ???x???x?? mm

= Character Set ROMs =

Together with the customized keyboards, the BIOS ROMs character sets were changed accordingly. The new characters are potentially useful for home-use, but may result in compatibility problems when importing/exporting software to/from other countries - or even within the same country (the new character sets were invented around 1986, so older french/spanish/danish CPCs didn't support the new symbols).

== English ==
[[File:Charset english gray.gif|left]]
'''English BIOSes'''
* 40009 English 464
* 40022 English 664
* 40025 English 6128
* 41???-? English Plus (EPROM in System Cartridge)
'''Default Symbols'''
The english BIOSes are also used in german models. Until around 1986 (when localized keyboards/BIOSes were invented), the english BIOSes were also used in spanish/french/danish CPCs.
 

== French ==
[[File:Charset french gray.gif|left]]
'''French BIOSes'''
* 40050 French 464
* 40051 French 6128
* 130Z001 41090-1 French Plus (EPROM in System Cartridge)
'''Special Symbols'''
* chr(40h) "à" instead "@"
* chr(5Ch) "ç" instead "\"
* chr(5Eh) "^" with different shape
* chr(7Bh) "é" instead "{"
* chr(7Ch) "ù" instead "|"
* chr(7Dh) "è" instead "}"
* chr(82h) "°" instead umlaut symbol
Changed chr(7Ch) means RSX commands become ùCPM instead |CPM.
The keyboard itself does have both "ù" and "|" keys, but, the default BIOS/BASIC tables do map "ù" to both of them.
 

== Spanish ==
[[File:Charset spanish gray.gif|left]]
'''Spanish BIOSes'''
* 40037 Spanish 464/472
* 40038 Spanish 6128
* 130Z001 41091-1 Spanish Plus (EPROM in System Cartridge)
'''Special Symbols'''
* chr(81h) "Ñ" instead "´"
* chr(83h) "Pt" instead "£"
* chr(8Bh) "ñ" instead "±"
The changed pound/peseta currency symbol may result in some confusion, since the actual exchange rate is unlikely to be 1:1.
 

== Danish ==
[[File:Charset danish gray.gif|left]]
'''Danish BIOSes'''
* 40??? Danish 464
* 40??? Danish 6128
* 40???-? Danish Plus (probably doesn't exist?)
'''Special Symbols'''
* chr(30h) non-slashed zero, to avoid confusion with letter "Ø"
* chr(5Bh) "Æ" instead "["
* chr(5Ch) "Ø" instead "\"
* chr(5Dh) "Å" instead "]"
* chr(7Bh) "æ" instead "{"
* chr(7Ch) "ø" instead "|"
* chr(7Dh) "å" instead "}"
Similar as in french, RSX commands like "|CPM" become "øCPM".
 

= Notes =

* According to soft968 the official language variants are: Spanish, French and Danish. And, presumably, English was official, too.

* Although french/danish charsets don't support "|", even newer user manuals (like french cpc+ manual from 1990) still refer to RSX commands as "|CPM" and describe to press shift+"@" to get the "|".
