LK Links

2010-10-07T17:12:37Z

Nocash: Undo revision 61602 by TFM - AMSDOS uses CALL B912 for deciding whether to boot CPM, as far as known AMSDOS doesn't check PPI inputs, so LK5 must affect ROM banking - correct me if that's wrong!

'''Links''' - Amstrad has used a number of LKs (Links) on CPC mainboards and on peripherals like DDI-1 and CPC+ Cartridges. The LKs are simply a piece of wire that is (or is not) installed between two soldering points.

'''Resistors''' - The CPC+ does additionally have some optional 10kOhm resistors with similar functions (they connect to the ASICs MUX pins, which are used as configuration input (affected by the resistor), and as ADC channel select output (not affected by the resistor; but won't work when using wires instead of resistors). Note: In schematics, these resistors are labeled R128,R129,R130 - but, on the mainboard they are labeled R28,R29,R30.

== LK1,LK2,LK3 - Manufacturer ID ==

LK1,LK2,LK3 connect to [[8255|PPI]] Port B, Bit1-3. The links select the manufacturer name (which is displayed by the BIOS in the power-up message). These LKs exist on all CPC mainboards (in CPC Plus/GX4000 schematics they are named LK101,LK102,LK103). By default, LK1-LK3 are not installed ([[Amstrad]]). Other combinations are LK2 installed in german [[Schneider]] models, and LK1+LK2 in australian [[Awa]] models. For more info see [[LK-selectable Brand Names]].

== LK4 - Screen Refresh Rate ==

LK4 connects to [[8255|PPI]] Port B, Bit4. The link tells the BIOS whether it should set-up the [[CRTC]] for 50Hz or 60Hz refresh rate.
Default is LK4 not installed (50Hz).

It might be installed in US models, there isn't too much known about whether CPCs were exported to USA.... One source says that the CPC6128 was initially sold ''only'' in USA... Another source says that Indescomp (spanish distributor) produced CPCs with ''Indescomp International U.S.A.'' stickers.

The 60Hz setting may cause compatibility problems with various non-BIOS software. And, due to a BIOS glitch, even with BIOS-based software (see [[Media:S968ap13.pdf|SOFT 968 Appendix 13 (XIII) (Hints Tips and Workarounds)]] for details).

== CPC6128:LK5,LK6,LK8 - Disable 128K RAM Banking ==

The CPC6128 contains 128K RAM, RAM banking is controlled by a PAL (which assists its [[Gate Array]]). However, the 6128 mainboard can be also used for 64K computers - in that case, only 64K would be installed, the PAL would be missing, and LK5,LK6,LK8 would be installed (bypassing the RAM banking logic, and passing /CAS,A14,A15 signals directly to unbanked RAM). The CPC+ has a similar feature (see R128 below).

== DDI-1:LK1 - Autoboot CP/M ==

In the DDI-1, LK1 connects '''both''' to the Expansion Port /EXP pin (which goes to [[8255|PPI]] Port B, Bit5, '''and''' to the AMSDOS ROM bank number selection logic. The latter one allow to map AMSDOS to bank 7 (default), or bank 0. If AMSDOS sees itself mapped to bank 0, then it does automatically load & start the boot sector from drive A (equivalent as when typing |CPM after power-up).

== DDI-1:LK2,LK3 - Disc Write Precomp ==

In DDI-1, LK2-LK3 connect to the P1/P0 pins of the FDC9229BT Disc Data Separator (P0=LK3, P1=LK2, and fixed: P2=GND). According to FDC9229BT datasheet: ''P2-P0 select the amount of precompensation applied to the write data''.

== CPC6128:LK7 aka CPC664:LK201 - Autoboot CP/M ==

Same as DDI-1:LK1 (see there). By default, the two soldering points are connected with each other (by a printed wire on the PCB, to activate autoboot one must scratch off that connection).
In the CPC664, LK201 is located close to the power-supply connectors.
In the CPC6128, LK7 is located close to the gate array.

== CPC Plus:LK105 - Autoboot CP/M ==

Same as DDI-1:LK1 (see there). '''Bug:''' There's a bug in the System Cartridge, which always attempts to execute the Burnin' Rubber bootmenu at address 7:C072h, this is done even if bank 0 and 7 are exchanged, causing the CPC to crash when LK105 is changed. Workaround would be to replace opcode LD C,07h (at 05EBh in system cart) by LD C,83h (this fixes the bug), or to replace opcode LD HL,C072h (at 05E8h in system cart) by LD HL,0000h (completely disables the bootmenu, which was a rather idea annoying anyways). The same bug occurs when [[Connecting a Disc Interface to CPC464+]].

== CPC Plus:LK106 - Unknown ==

Purpose unknown...? Usually LK106 is not installed. (related to Upper ROM Bank signals /IORQ, A13, /WAIT, /RESET)

== CPC Plus:R128 aka R28 (10kOhm) - 128K RAM Enable ==

Installed for 128K DRAM, not installed for 64K DRAM.

== CPC Plus:R129 aka R29 (10kOhm) - Disc Vers Enable ==

'''Purpose Unknown !!!'''
* The ASIC (where R129 connects to) should have nothing to do with the FDC. However, it does control the AMSDOS ROM bank selection: translating ROM bank 7 (or 0) to cartridge bank 3. However, bank 7 is used by the Burnin' Rubber boot-menu, so bank 7 must exist regardless of R129.
* The ASIC does output some FDC related signals /MOTOR and /FDC. Maybe removing R129 disables these, though that would be of not too much use (unless one wants to disable an internal FDC, in order to use an external FDC instead of it).
This is not verified, can somebody test what happens when installing/removing R129 ?

== CPC Plus:R130 aka R30 (10kOhm) - 8bit Printer Enable ==

When installed (default), enables the 8th printer bit, controlled via [[CRTC]] Register 0Ch, Bit 3.
When removed, outputs LOW as 8th bit (as on classic CPCs with 7bit printer port).
See also: [[8bit Printer Ports]].

== CPC Plus Cartridges:LK1-LK6 - EPROM Address Lines ==

The six [[GX4000 cartridge|cartridge]] LKs are for A15,A17,A18 (address lines, of course, not the "A1-A18" pins).
VCC ---LK1--- EPROM.A18 ---LK2--- CA18
VCC ---LK3--- EPROM.A17 ---LK4--- CA17
VCC ---LK5--- EPROM.A15 ---LK6--- CA15
Some cartridge PCBs don't have any LKs installed, instead, the etched circuit has hardwired connections between some of them. One could scratch them off, and then use the LK soldering points to reconfigure the board for eproms of other size.

== GX4000:LKs ==

* LK1-LK4 - same as CPC, though not being actually used, due to absent BIOS (though game cartridges could check LK4 to determine the desired video refresh rate) (default is LK1-LK4 not installed, equivalent to Video=50Hz, and Manufacturer=Amstrad)
* LK5 - none such (corresponding PPI input is floating, neither having a LOW level, nor a stable HIGH level) (meaning the ROM Bank0=BASIC and Bank7=AMSDOS are unstable on GX4000, this seems to be the reason for the CPC+ System Cartridge not booting properly on the GX4000)
* LK6 - unknown (same as LK106 on CPC+) (usually LK6 is not installed, neither in GX4000 nor CPC+)
* LK7 - shortcut +5V with +5VMOD (installed in french version, which has no TV modulator)

Schneiderware Basisplatine

2010-10-02T16:53:35Z

Nocash:

The [[Schneiderware Basisplatine]] (backplane) is some kind of a [[ECB Bus]] motherboard for the [[Schneiderware]] DIY series, which was published by german magazine [[CPC Schneider International]]. The board has five 64-pin ECB sockets (for use with the DIY boards of the series), a 50-pin connector (for the CPC expansion port), and 7 soldering points (for an optional power supply, like the [[Schneiderware Power Supply]]).

The plain PCB, or the fully assembled board were available via mail-order. Unlike as for the other DIY projects of the Schneiderware series, the PCB layout has not been printed (in paper-form) in the magazine (though the magazine offered to send them to interested persons). Another solution would have been to buy a standard ECB backplane (like [[:File:Reichelt Euro-Bus-Karte.jpg|this]]), and to build an adaptor for the CPC expansion port by hand.

Schneiderware

2010-10-02T16:50:34Z

Nocash:

The [[Schneiderware]] series consists of several DIY projects which have been released 1986-1987 in german magazine [[CPC Schneider International]] published by [[DMV]]. The name "Schneiderware" was probably choosen due to its double meaning ("CPC Hardware" in computer language, or "designer clothing" in german language). Aside from building the hardware on one's own, one could also order printed circuit boards, either fully assembled, or plain PCBs without components.

The various boards are having special connectors, intended to be mounted on the "Basisplatine" (some kind of a motherboard with [[ECB Bus]] sockets) which allows to connect up to five Schneiderware boards to the CPCs Expansion Port; with some small modifications one could also connect the boards directly to the Expansion Port (the motherboard is merely an Y-cable-like adaptor without electrical components, so one doesn't really need it).

Schneiderware Introduction

2010-10-02T15:15:59Z

Nocash:

Part 1 of the [[Schneiderware]] DIY series from Peter Richter released by german magazine [[CPC Schneider International]] contained some theoretical background on the DIY projects that followed in the next issues.

The introduction explained basic questions - like "what is a data bus? what is an addresss bus? what are control signals? what are AND and OR gates?" and so on.

== Scanned Article ==

* [[Media:Schneiderware 1 - Intro.pdf|Schneiderware 1 - Intro.pdf]] - Theory - '''6/1986 page 62-67''', plus preface from 5/1986 page 21, final notes from 11/1987 page 97-99

== About the Schneiderware Series ==

Whilst the series was aimed at beginners, the DIY schematics could have been a bit less cryptic: They often only showed only low-level details like "Pin 123 wired to Pin4 of IC6" - some additional comments with signal & chip names would have made it much easier to see that, for example, "/IOREQ is wired to an OR gate". One could eventually extract that info from other sections of the article, and, when doing that, one may have really learned something.

Some articles also contained barely described jumpers, undocumented I/O addresses, and example programs in machine code (as hex dumps since printing the complete source code would require more pages), which meant that one needed to do some reverse engineering to understand the software and hardware. For some projects, the source code was released on the magazines Databoxes that could be purchased optionally (instead of entering the type-in listings).

Schneiderware Power Supply

2010-10-02T15:05:45Z

Nocash: /* Alternate Versions */

The [[Schneiderware Power Supply]] is an external power supply published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

== Description ==

The power supply is needed only for Schneiderware projects that do require special voltages, or for projects that do overload the CPC's own +5V supply (which may happen when connection too many expansion boards, for example). The supply outputs the following voltages:

* +5V DC - needed only when the CPC's built-in supply gets overloaded
* +12V DC - needed for the [[Schneiderware V/24 Interface]] and the [[Schneiderware Analog Converter]]
* -12V DC - needed for the [[Schneiderware V/24 Interface]] only
* +24V DC - not used (was intended for the EPROM Burner, but when the EPROM burner was released, it contained a 5V-to-25V converter, and thus didn't need the +24V anymore)

Aside from the components on the PCB, one does also need a transformator, which isn't shown on the photos. Despite of being a very important component, the DIY article contained only few side-notes on the transformator. The thing must provide a number of AC voltages, and it might be difficult to find a matching transformator (one could get one from the magazine via mail-order, but it wasn't cheap).

== Connection Cautions ==

The supply uses the same type of 2x32 pin connector as the other Schneiderware boards, however, the supply is '''NOT''' intended to be plugged into the [[ECB Bus]] sockets, instead, it should be wired to the 7 soldering points on the [[Schneiderware Basisplatine]].

Namely, it connects to the three GND pins, and the 5V, and -/+12V pins. The seventh pin, "AC", is left unused (it's been intended for rechargeable "ACCU" batteries, but the later RTC and SRAM projects contained their own batteries, and didn't use the "AC" supply).

The CPC's internal +5V supply should be disconnected when connecting the external power-supply, otherwise something terrible might happen (for example, when one supply tries to output a few more volts than the other, or so).

The giant cooling plate (and the LM323K voltage regulator) aren't meant to be mounted directly on the PCB, but rather stacked a few centimenters above of the PCB (can be seen on photos in some of the later adverts).

== Alternate Versions ==

There seem to have been one or two alternate versions:

* The photo in the original article showed a different PCB with Gl1 and Gl2 differently arranged. And, the whole design is somehow mirrored or rotated (looks as if the components are installed on the solder side). That photo may have been a prototype, or faked dummy for illustration purposes. Later adverts are showing the "normal" Gl1/Gl2 arrangement.
* The magazine later released a correction on their Letters page which recommended to replace the 5K6 and 10K resistors on the L200 voltage converter - it sounded perfectly reasonable - except that, the DIY project doesn't contain any of that components. The correction (if it wasn't total nonsense) implies that the magazine shipped different PCBs to some people via their mail-order service.

And aside from the "official" Schneiderware supply, one could of course use any other suitable power supply. Nowadays, it would be easiest and cheapest to use an outsorted PC power supply, which provides perfectly regulated +5V, +12V and -12V with more than enough Amperes.

|DFxxh || N/A || [[Schneiderware Pseudo ROM|Schneiderware RAM/EPROM]] - Expansion ROM bank number (W) Battery-backed SRAM and/or EPROM are selected when the bank-number matches the jumper-selected values; the memory is then mapped to C000h..FFFFh (in case of READing one must also enable upper ROM via Gate Array). The bank number decoding is a bit strange:
* EPROM/Read bank: All 8 bits decoded (bank 00h..FFh)
* SRAM/Read bank: Only lower 4 bits decoded (bank X0h..XFh)
* SRAM/Write bank: Only lower 4 bits decoded (bank X0h..XFh)
The SRAM/Write mode doesn't disable the internal RAM in the CPC, so writes are going both to SRAM and normal RAM at C000-FFFF, that no matter if upper ROM is enabled/disabled via Gate Array; the author recommended to map VRAM to 4000-7FFF via CRTC registers, in order to prevent video dirt during writing.

Schneiderware Pseudo ROM

2010-10-02T03:55:16Z

Nocash: /* I/O Ports */

The [[Schneiderware Pseudo ROM]] is a expansion "ROM" board, with 16K EPROM (read-only) and 16K battery-backed SRAM (read/write-able), published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port.

8bit Printer Ports

2010-10-02T03:48:07Z

Nocash: /* External Printer Ports */

The CPC [[Printer Port]] has only 7 bit data. Which is sufficient for english 7 bit ASCII character sets, but not enough for 8 bit character sets. Also, printing bitmap graphics usually requires 8 bit data (though usually can also print 7 pixels columns combined with a reduced line-feed rate). Amstrad's DMP1 works perfectly with 7 bit, but Amstrad's later DMP2000/DMP2160 include a few functions that won't work on 7 bit ports - so even the official CPC printers aren't fully compatible with the CPC printer port.

== Internal 8 bit Printer Ports/Mods ==

=== Happy Computer 8 bit Printer Port upgrade (DIY) ===
A good method to upgrade to full 8 bit has been described in the german magazine "[[Happy Computer (Schneider Sonderheft)]] 2/85 and 4/86":
* Disconnect the D7 pin from ground, and wire it to the [[8255|PIO]]s Tape WR DATA pin instead (That is, Pin 12 of the 8255 chip).

Sharing that pin will cause no problems (as long as you do not attempt to send data to the tape drive and to printer at the same time). Of course, you will also have to customize your software, or BIOS ROM, or the BIOS jump vectors in RAM, in order to take advantage of the modification. In contrast, this DIY is supported by [[FutureOS]].

* For details see: [[Happy Computer 8bit Printer Mod]]

=== CPC Schneider International - 8 bit Printer Port Mod ===

DIY from [[CPC Schneider International]] (issue 12'85, page 64), this solution uses joystick port pin 8 (or (keyboard?) pin 2, unclear?).
* For details see: [[CPCI 8bit Printer Mod]]

=== PC Amstrad International - 8 bit Printer Port Mod ===

DIY from [[PC Amstrad International]] (issue 8/9'91, page 69-70), this solution uses PPI.Pin12 (same as the [[Happy Computer 8bit Printer Mod]]).

=== 8 bit Printer Port in KC Compact ===

The [[KC Compact]] uses the bit 5 of [[8255|PPI]] Port C as 8th printer bit (this is same as the Happy Computer mod, see above). Although the 8th bit is a built-in feature, the KC Compact Firmware doesn't support it. But it's supported by [[FutureOS]].

=== 8 bit Printer Port in Aleste 520EX ===

The [[Aleste 520EX]] includes an 8bit printer port, using PSG Ext Port B for data (which does not exist on the CPC), and PPI port C, Bit 4 for strobe (which would be Tape Motor in CPC). The Aleste doesn't have the normal CPC-style [[Printer Port]] at Port EFXXh. The BIOS functions are patched accordingly; including for supporting the 8th bit (unlike the CPC Plus and KC Compact, which do not support the 8th bit in BIOS functions).

=== 8 bit Printer Port in CPC Plus ===
In the CPC Plus, Bit 3 of [[CRTC]] Register 0Ch can be used as eighth printer bit. For compatibility to normal CPCs, this feature can be disabled by removing the 10 kOhm resistor R30 on the mainboard (aka R130 in the schematic). See [[LK Links]] for more info. Although the 8th bit is a built-in feature, the CPC Plus Firmware doesn't support it. However the 8 bit printer port of the CPC Plus is supported by [[FutureOS]].

Schneiderware Centronics Port

2010-10-02T03:41:36Z

Nocash: /* I/O Ports */

The [[Schneiderware Centronics Port]] is an external [[8bit Printer Ports|8bit Printer Port]], published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port.

* [[Schneiderware Centronics Port|Schneiderware #2b Centronics (Printer Port)]] (7/1986 pages 60-67, plus complaints from 10/1986 page 10, port B redefined on 12/1986 page 124 and 3/1987 pages 8-9)

== I/O Ports ==

Default I/O Address is F8E0h-F8E3h. An alternate I/O Address is jumper select-able (intended to allow to connect two Centronics cards to the computer), the alternate address was originally defined as F8F0h-F8F3h, but the later [[Schneiderware Uni-PIO|Schneiderware #6 Uni-PIO]] project did accidently use that addresses, too. In result, it was somewhat suggested (or silently implied) to change the secondary Centronics address to F8E4h-F8E7h.

{|{{Prettytable|width: 700px; font-size: 2em;}}
|Address (default) || Address (alternate) || Usage
|-
|F8E0h || F8F0h (later redefined to F8E4h) || Schneiderware Centronics [[8255 PPI chip|8255 PPI]] Port A (data)
|-
|F8E1h || F8F1h (later redefined to F8E5h) || Schneiderware Centronics [[8255 PPI chip|8255 PPI]] Port B (unused)
|-
|F8E2h || F8F2h (later redefined to F8E6h) || Schneiderware Centronics [[8255 PPI chip|8255 PPI]] Port C (busy/strobe) (bit7=busy, bit6-1=unused, bit0=strobe; strobe is externally inverted) (autolf is wired to GND, all other control/status signals are not connected)
|-
|F8E3h || F8F3h (later redefined to F8E7h) || Schneiderware Centronics [[8255 PPI chip|8255 PPI]] Control
|-

Using a [[8255 PPI chip]] with 24 I/O lines is possibly the most expensive and overcomplicated 8bit Printer Port solution, especially as the circuit uses only 10 of the 24 signals (it implements only Data, Strobe, and Busy - other Centronics signals like Error, Ack, Select, etc. aren't connected).

'''Note''' - The same magazine released a number of different [[8bit Printer Ports|8bit Printer Port]] solutions: A [[CPCI 8bit Printer Mod|joystick-signal based one]] (simple & messy), the Happy Computer [[Happy Computer 8bit Printer Mod|cassette-write based one]] (simple & elegant), and the [[Schneiderware]] one (complex & expensive).

== More Ports ==

Some more I/O addresses (which aren't included in the above list yet) are here:
* [[Schneiderware Summary]]

== Other I/O Ports ==

A number of peripherals connect to the joystick/printer ports, and so, they do not include "own" I/O addresses. This includes hardware ''other than joysticks/printers'' - for example, mice, robots, audio devices, and simple network adapters. For a more complete list, see corresponding sections on [[Digital Joysticks|Digital Joystick]] and [[Printer Port]] pages.

Aside from I/O addresses, there are some other important I/O signals, for example: [[NMI]] or [[External Interrupt|INT]].

== Other Ports ==

Some more I/O addresses (which aren't included in the above list yet) are here:
* [[Schneiderware Summary]]

== Other I/O Ports ==

A number of peripherals connect to the joystick/printer ports, and so, they do not include "own" I/O addresses. This includes hardware ''other than joysticks/printers'' - for example, mice, robots, audio devices, and simple network adapters. For a more complete list, see corresponding sections on [[Digital Joysticks|Digital Joystick]] and [[Printer Port]] pages.

Aside from I/O addresses, there are some other important I/O signals, for example: [[NMI]] or [[External Interrupt|INT]].

Schneiderware Introduction

2010-10-02T03:20:30Z

Nocash:

Part 1 of the [[Schneiderware]] DIY series from Peter Richter released by german magazine [[CPC Schneider International]] contained some theoretical background on the DIY projects that followed in the next issues.

The introduction explained basic questions - like "what is a data bus? what is an addresss bus? what are control signals? what are AND and OR gates?" and so on.

Whilst the series was aimed at beginners, the later DIY schematics could have been a bit less cryptic: They often only showed only low-level details like "Pin 123 wired to Pin4 of IC6" - some additional comments with signal & chip names would have made it much easier to see that, for example, "/IOREQ is wired to an OR gate". One could eventually extract that info from other sections of the article, and, when doing that, one may have really learned something.

Some articles also contained barely described jumpers, undocumented I/O addresses, and example programs in machine code (as hex dumps since printing the complete source code would require more pages), which meant that one needed to do some reverse engineering to understand the software and hardware. For some projects, the source code was released on the magazines Databoxes that could be purchased optionally (instead of entering the type-in listings).

Schneiderware

2010-10-02T02:50:10Z

Nocash:

The [[Schneiderware]] series consists of several DIY projects which have been released 1986-1987 in german magazine [[CPC Schneider International]] published by [[DMV]]. The name "Schneiderware" was probably choosen due to its double meaning ("CPC Hardware" in computer language, or "specially fitted clothing" in german language). Aside from building the hardware on one's own, one could also order printed circuit boards, either fully assembled, or plain PCBs without components.

The various boards are having special connectors, intended to be mounted on the "Basisplatine" (some kind of a motherboard with [[ECB Bus]] sockets) which allows to connect up to five Schneiderware boards to the CPCs Expansion Port; with some small modifications one could also connect the boards directly to the Expansion Port (the motherboard is merely an Y-cable-like adaptor without electrical components, so one doesn't really need it).

Schneiderware EPROM Burner

2010-10-02T02:47:10Z

Nocash:

The [[Schneiderware EPROM Burner|Schneiderware Eprommer]] is a EPROM Burner, it supports 24pin and 28pin chips (max 32K bytes), published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port. The required EPROM programming voltages are generated by a 5V to 25V converter (and, where needed, lowered to 21V or 12.5V), so one doesn't need an external power supply. The programmed EPROMs can be used (among others) with the [[Schneiderware Pseudo ROM|Schneiderware ROM/EPROM board]].

Schneiderware Pseudo ROM

2010-10-02T02:46:10Z

Nocash:

The [[Schneiderware Pseudo ROM]] is a expansion "ROM" board, with 16K EPROM (read-only) and 16K battery-backed SRAM (read/write-able), published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port.

== I/O Ports ==

|DFxxh || Schneiderware RAM/EPROM - [[Upper ROM Bank Number|Expansion ROM bank number]] (W) Battery-backed SRAM and/or EPROM are selected when the bank-number matches the jumper-selected values; the memory is then mapped to C000h..FFFFh (in case of READing one must also enable upper ROM via Gate Array). The bank number decoding is a bit strange:
* EPROM/Read bank: All 8 bits decoded (bank 00h..FFh)
* SRAM/Read bank: Only lower 4 bits decoded (bank X0h..XFh)
* SRAM/Write bank: Only lower 4 bits decoded (bank X0h..XFh)
The SRAM/Write mode doesn't disable the internal RAM in the CPC, so writes are going both to SRAM and normal RAM at C000-FFFF, that no matter if upper ROM is enabled/disabled via Gate Array; the author recommended to map VRAM to 4000-7FFF via CRTC registers, in order to prevent video dirt during writing.
|-

'''Note''' - Port DFxxh is the standard [[Upper ROM Bank Number]] register, which is also used by [[AMSDOS]], for example. Reserved banks are 00h=Basic, and 07h=AMSDOS. Other bank numbers can be used by one (or more) Schneiderware Pseudo ROM board(s).

Schneiderware Analog Converter

2010-10-02T02:45:12Z

The [[Schneiderware Analog Converter]] is a A/D and D/A Converter with 8 analog inputs, 2 analog outputs, published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port. The D/A converter additionally requires a [[Schneiderware Power Supply]] (or another external power supply with +12V) (eventually one could also use the CPC's disc drive power supply; though not tested if the supplies in the CTM644/GT65 monitors provide enough amps).

Schneiderware Uni-PIO

2010-10-02T02:44:37Z

Nocash: /* Article */

The [[Schneiderware Uni-PIO]] is a general purpose I/O port with 48 input/output signals, published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port.

== I/O Ports ==

Default I/O Addresses are F8E8h-F8EFh, optionally a second or third Uni-PIO card can be jumpered to F8F0h-F8F7h and F8F8h-F8F8h, giving a total of 144 I/O lines when using three cards.

|-
|}

'''Cautions''' - Port F8F0h-F8F3h were also used as alternate address of the [[Schneiderware Centronics Port]], recommended work-around is to modify the Centronics card. On the PCBs, two PPI #1 Port C signals are accidently exchanged with each other (wired to the wrong pins on the 50-pin connector, and to the wrong LEDs).

Schneiderware Real Time Clock

2010-10-02T02:43:58Z

Nocash: /* Article */

The [[Schneiderware Real Time Clock]] is a battery-backed RTC, published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port.

== I/O Ports ==

{|{{Prettytable|width: 700px; font-size: 2em;}}

|FBE3h || BUGGED:FBE2h || Schneiderware RTC data 4bit (W)
|-
|FBE4h || BUGGED:FBE3h || Schneiderware RTC data 4bit (R)
|-
|}

'''Note''' - The Schneiderware Real Time Clock is somewhat similar to the [[Real Time Clock|CPCI Real Time Clock]] released in a special issue of the same magazine, but not identical (the RTC chip has different pin-outs, and some of it's 4bit registers are working slightly different, the leap-year bits, for example).
The I/O ports are also slightly different: The Schneiderware version has additional control bits in port FBE2h, and, for whatever reason, it splits data to two separate addresses (for FBE3h for writing, and FBE4h for reading), rather than mapping both to FBE3h.

== Software ==

'''Caution''' - The listing in the magazine (and the databox files) are bugged and won't work: The I/O addresses are wrong. Additionally, some function entrypoints seem to be accidently set to 0000h.

Databoxes: '''UHR8000''' RTC-RAM-driver in 10-1986 (hex listing, plus [[Hisoft Devpac]] source code) (caution this version uses incorrect I/O addresses FBE1-FBE3), '''UHRC000X''' RTC-ROM-driver in 4-1987 (this version uses correct I/O addresses FBE2-FBE4).

Schneiderware Power Supply

2010-10-02T02:43:19Z

Nocash:

The [[Schneiderware Power Supply]] is an external power supply published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

== Description ==

The power supply is needed only for Schneiderware projects that do require special voltages, or for projects that do overload the CPC's own +5V supply (which may happen when connection too many expansion boards, for example). The supply outputs the following voltages:

* +5V DC - needed only when the CPC's built-in supply gets overloaded
* +12V DC - needed for the [[Schneiderware V/24 Interface]] and the [[Schneiderware Analog Converter]]
* -12V DC - needed for the [[Schneiderware V/24 Interface]] only
* +24V DC - not used (was intended for the EPROM Burner, but when the EPROM burner was released, it contained a 5V-to-25V converter, and thus didn't need the +24V anymore)

Aside from the components on the PCB, one does also need a transformator, which isn't shown on the photos. Despite of being a very important component, the DIY article contained only few side-notes on the transformator. The thing must provide a number of AC voltages, and it might be difficult to find a matching transformator (one could get one from the magazine via mail-order, but it wasn't cheap).

== Connection Cautions ==

The supply uses the same type of 2x32 pin connector as the other Schneiderware boards, however, the supply is '''NOT''' intended to be plugged into the [[ECB Bus]] sockets, instead, it should be wired to the 7 soldering points on the [[Schneiderware Basisplatine]].

Namely, it connects to the three GND pins, and the 5V, and -/+12V pins. The seventh pin, "AC", is left unused (it's been intended for rechargeable "ACCU" batteries, but the later RTC and SRAM projects contained their own batteries, and didn't use the "AC" supply).

The CPC's internal +5V supply should be disconnected when connecting the external power-supply, otherwise something terrible might happen (for example, when one supply tries to output a few more volts than the other, or so).

The giant cooling plate (and the LM323K voltage regulator) aren't meant to be mounted directly on the PCB, but rather stacked a few centimenters above of the PCB (can be seen on photos in some of the later adverts).

== Alternate Versions ==

There seem to have been one or two alternate versions:

* The photo in the original article showed a different PCB with Gl1 and Gl2 differently arranged. That photo may have been a dummy/prototype. Later adverts are showing the "normal" Gl1/Gl2 arrangement.
* The magazine later released a correction on their letters page which recommended to replace the 5K6 and 10K resistors on the L200 voltage converter - it sounded perfectly reasonable - except that, the DIY project doesn't contain any of that components. The correction (if it wasn't total nonsense) implies that the magazine shipped different PCBs to some people via their mail-order service.

And aside from the "official" Schneiderware supply, one could of course use any other suitable power supply. Nowadays, it would be easiest and cheapest to use an outsorted PC power supply, which provides perfectly regulated +5V, +12V and -12V with more than enough Amperes.

Schneiderware V/24 Interface

2010-10-02T02:42:31Z

Nocash: /* Article */

The [[Schneiderware V/24 Interface]] is a [[RS232]] Interface, published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port. The V/24 board additionally requires a [[Schneiderware Power Supply]] (or another external power supply with +12V/-12V).

== I/O Ports ==

Default I/O Addresses are F9E0h-F8E1h and F9ECh-F9EFh (ie. the lowest and highest addresses in the F9E0h-F9EFh region). Alternately, addresses F9E2h-F8E3h and F9E8h-F9EBh (ie. the '''middle''' addresses in the F9E0h-F9EFh region) are jumper select-able (intended to allow to connect two RS232 cards to the computer).

{|{{Prettytable|width: 700px; font-size: 2em;}}
|Address (default) || Address (alternate) || Usage

|-
|}

== Jumper Problems ==

'''Caution''' - The '''clock source''' can be jumpered to 2MHz (default), or to 1MHz. Moreover, the '''handshaking''' signals (CTS/RTS, DTR/DSR) can be disabled via jumpers. There is no good reason for using the 1MHz setting, nor for disabling handshaking at hardware level - these features are only "good" for provoking compatibility problems with software that expects the jumpers to be set to this or that position.

For the more bizarre part, the handshaking signals are '''disabled''' by default. And, these pre-defined settings are implemented as '''hardwired''' connections on the '''component''' side of the PCB; meaning that one cannot cut these connections once when the components (jumpers) are installed on the PCB. About 15 months later, in issue 11-1987, the author did admit that they shipped fully assembled PCBs without cutting these "hidden" connections underneath of the jumpers.

Aside from that, both the PCB and the original schematic haven't been too clear about which pins on the 4-pin jumpers should be connected together (and which of the predefined horizontal & vertical connections should be disconnected). Without good reverse-engineering skills it's been rather frustating (if not impossible) to find the correct jumper settings.

Schneiderware Centronics Port

2010-10-02T02:41:35Z

Nocash:

The [[Schneiderware Centronics Port]] is an external [[8bit Printer Ports|8bit Printer Port]], published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port.

* [[Schneiderware Centronics Port|Schneiderware #2b Centronics (Printer Port)]] (7/1986 pages 60-67, plus complaints from 10/1986 page 10, port B redefined on 12/1986 page 124 and 3/1987 pages 8-9)

== I/O Ports ==

Default I/O Address is F8E0h-F8E3h. An alternate I/O Address is jumper select-able (intended to allow to connect two Centronics cards to the computer), the alternate address was originally defined as F8F0h-F8F3h, but the later [[Schneiderware Uni-PIO|Schneiderware #6 Uni-PIO]] project did accidently use that addresses, too. In result, it was somewhat suggested (or silently implied) to change the secondary Centronics address to F8E4h-F8E7h.

{|{{Prettytable|width: 700px; font-size: 2em;}}
|Address (default) || Address (alternate) || Usage
|-
|F8E0h || F8F0h (later redefined to F8E4h) || Schneiderware Centronics [[8255 PPI chip|8255 PPI]] Port A (data)
|-
|F8E1h || F8F1h (later redefined to F8E5h) || Schneiderware Centronics [[8255 PPI chip|8255 PPI]] Port B (unused)
|-
|F8E2h || F8F2h (later redefined to F8E6h) || Schneiderware Centronics [[8255 PPI chip|8255 PPI]] Port C (busy/strobe) (bit7=busy, bit6-1=unused, bit0=strobe; strobe is externally inverted) (autolf is wired to GND, all other control/status signals are not connected)
|-
|F8E3h || F8F3h (later redefined to F8E7h) || Schneiderware Centronics [[8255 PPI chip|8255 PPI]] Control
|-
|}

Using a [[8255 PPI chip]] with 24 I/O lines is possibly the most expensive and overcomplicated 8bit Printer Port solution, especially as the circuit uses only 10 of the 24 signals (it implements only Data, Strobe, and Busy - other Centronics signals like Error, Ack, Select, etc. aren't connected).

'''Note''' - The same magazine released a number of different [[8bit Printer Ports|8bit Printer Port]] solutions: A [[CPCI 8bit Printer Mod|joystick-signal based one]] (simple & messy), the Happy Computer [[Happy Computer 8bit Printer Mod|cassette-write based one]] (simple & elegant), and the [[Scheiderware]] one (complex & expensive).

Schneiderware Basisplatine

2010-10-02T02:39:39Z

Nocash:

The [[Schneiderware Basisplatine]] (backplane) is some kind of a [[ECB Bus]] motherboard for the [[Schneiderware]] DIY series, which was published by german magazine [[CPC Schneider International]]. The board has five 64-pin ECB sockets (for use with the DIY boards of the series), a 50-pin connector (for the CPC expansion port), and 7 soldering points (for an optional power supply, like the [[Schneiderware Power Supply]]).

The plain PCB, or the fully assembled board were available via mail-order. Unlike as for the other DIY projects of the Schneiderware series, the PCB layout has not been printed (in paper-form) in the magazine (though the magazine offered to send them to interested persons). Another solution would have been to buy a standard ECB backplane (like [[:File:Reichelt Euro-Bus-Karte.jpg|this]]), and to build an adaptor for the CPC expansion port by hand.

The bank number decoding is a bit strange:
* EPROM/Read bank: All 8 bits decoded (bank 00h..FFh)
* SRAM/Read bank: Only lower 4 bits decoded (bank X0h..XFh)

The SRAM/Write mode doesn't disable the internal RAM in the CPC, so writes are going both to SRAM and normal RAM at C000-FFFF, that no matter if upper ROM is enabled/disabled via Gate Array; the author recommended to map VRAM to 4000-7FFF via CRTC registers, in order to prevent video dirt during writing.

Schneiderware

2010-10-02T02:21:46Z

Nocash:

The [[Schneiderware]] series consists of several DIY projects which have been released in german magazine [[CPC Schneider International]] published by [[DMV]]. The name "Schneiderware" was probably choosen due to its double meaning ("CPC Hardware" in computer language, or "specially fitted clothing" in german language). Aside from building the hardware on one's own, one could also order printed circuit boards, either fully assembled, or plain PCBs without components.

The various boards are having special connectors, intended to be mounted on the "Basisplatine" (some kind of a motherboard with [[ECB Bus]] sockets) which allows to connect up to five Schneiderware boards to the CPCs Expansion Port; with some small modifications one could also connect the boards directly to the Expansion Port (the motherboard is merely an Y-cable-like adaptor without electrical components, so one doesn't really need it).

|-
|DFxxh || N/A || [[Schneiderware Pseudo ROM|Schneiderware RAM/EPROM]] - Expansion ROM bank number (W) Battery-backed SRAM and/or EPROM are selected when the bank-number matches the jumper-selected values; the memory is then mapped to C000h..FFFFh (in case of READing one must also enable upper ROM via Gate Array). The bank number decoding is a bit strange:
* EPROM/Read bank: All 8 bits decoded (bank 00h..FFh)
* SRAM/Read bank: Only lower 4 bits decoded (bank X0h..XFh)
* SRAM/Write bank: Only lower 4 bits decoded (bank X0h..XFh)
The SRAM/Write mode doesn't disable the internal RAM in the CPC, so writes are going both to SRAM and normal RAM at C000-FFFF, that no matter if upper ROM is enabled/disabled via Gate Array; the author recommended to map VRAM to 4000-7FFF via CRTC registers, in order to prevent video dirt during writing.

Schneiderware V/24 Interface

2010-10-02T02:12:54Z

Nocash: /* Jumper Problems */

The [[Schneiderware V/24 Interface]] is a [[RS232]] Interface, published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port. The V/24 board additionally requires a [[Schneiderware Power Supply]] (or another external power supply with +12V/-12V).

== I/O Ports ==

Default I/O Addresses are F9E0h-F8E1h and F9ECh-F9EFh (ie. the lowest and highest addresses in the F9E0h-F9EFh region). Alternately, addresses F9E2h-F8E3h and F9E8h-F9EBh (ie. the '''middle''' addresses in the F9E0h-F9EFh region) are jumper select-able (intended to allow to connect two RS232 cards to the computer).

{|{{Prettytable|width: 700px; font-size: 2em;}}
|Address (default) || Address (alternate) || Usage
|-
|F9E0h || F9E2h || Schneiderware V/24 [[8251 USART chip]] Data
|-
|F9E1h || F9E3h || Schneiderware V/24 [[8251 USART chip]] Control

== Jumper Problems ==

'''Caution''' - The '''clock source''' can be jumpered to 2MHz (default), or to 1MHz. Moreover, the '''handshaking''' signals (CTS/RTS, DTR/DSR) can be disabled via jumpers. There is no good reason for using the 1MHz setting, nor for disabling handshaking at hardware level - these features are only "good" for provoking compatibility problems with software that expects the jumpers to be set to this or that position.

For the more bizarre part, the handshaking signals are '''disabled''' by default. And, these pre-defined settings are implemented as '''hardwired''' connections on the '''component''' side of the PCB; meaning that one cannot cut these connections once when the components (jumpers) are installed on the PCB. About 15 months later, in issue 11-1987, the author did admit that they shipped fully assembled PCBs without cutting these "hidden" connections underneath of the jumpers.

Aside from that, both the PCB and the original schematic haven't been too clear about which pins on the 4-pin jumpers should be connected together (and which of the predefined horizontal & vertical connections should be disconnected). Without good reverse-engineering skills it's been rather frustating (if not impossible) to find the correct jumper settings.

Nocash: /* Schneiderware V/24 Interface */

== Registers ==

=== Control Register (W) ===
The first write after internal or external Reset is the "Mode Instruction":
Bit Expl.
0-1 Baud Rate Divider (0=Sync Mode, 1=Div1, 2=Div16, 3=Div64)
2-3 Character Length (0=5bit, 1=6bit, 2=7bit, 3=8bit)
4 Parity Enable (0=Disable, 1=Enable)
5 Parity Type (0=Odd, 1=Even)
In Async mode:
6-7 Stop Bits (0=Reserved, 1=1bit, 2=1.5bit, 3=2bit)
In Sync mode:
6 External Sync Detect (0=Syndet is an output, 1=Syndet is an input)
7 Single Character Sync (0=Double Character, 1=Single Character)
If (only if) the above 1st write selected Sync Mode, then 2nd/3rd write are:
2nd write - Sync Character 1
3rd write - Sync Character 2
All further writes to the Control Register are "Command Instructions":
Bit Expl.
0 Transmit Enable (0=Disable, 1=Enable)
1 Data Terminal Ready (0=No, 1=Yes) (DTR Pin)
2 Receive Enable (0=Disable, 1=Enable)
3 Send Break Character (0=Normal, 1=Force TxD "low")
4 Error Reset (0=No change, 1=Reset Error Flags)
5 Request to Send (0=No, 1=Yes) (RTS Pin)
6 Internal Reset (0=No change, 1=Reset; expect new Mode Instruction)
7 Enter Hunt Mode (0=No, 1=Search Sync Characters; Sync Mode only)

=== Status Register (R) ===
Bit Expl.
0 Transmit Ready (0=Busy, 1=Ready; "DB Buffer Empty")
1 Receive Ready
2 Transmit Empty
3 Parity Error
4 Overrun Error
5 Framing Error
6 Syndet/Brkdet
7 Data Set Ready (DSR Pin)

=== Data Register (R/W) ===
Bit Expl.
0-7 Data

== Usage in CPCs ==

=== Aleste 520EX ===
Used by [[Aleste 520EX]] (a CPC clone with built-in RS232 interface):
EEXXh Aleste - 8251 USART chip (RS232/Mouse) Data (R/W)
EFXXh Aleste - 8251 USART chip (RS232/Mouse) Control/Status (R/W)
Uses a KR580WW51A (russian clone of the 8251).
Clock source comes from a [[8253 chip]].

----

=== MHT Ingenieros RS232 para Amstrad ===
Used by [[RS-232 para Amstrad]] from MHT Ingenieros, mapped to Ports:
FADCh - MHT RS232 - 8251 USART data
FADDh - MHT RS232 - 8251 USART control/status
Clock source comes from a [[8253 chip]].

----

=== Schneiderware V/24 Interface ===
Used by [[Schneiderware V/24 Interface]] from [[CPC Schneider International]], mapped to Ports:
F9E0h (or F9E2h) Schneiderware V/24 8251 USART chip Data
F9E1h (or F9E3h) Schneiderware V/24 8251 USART chip Control
Clock source comes from a [[8253 chip]].
Clock input to that chip is jumper-selectable: 2MHz (default), or 1MHz.
Caution: The RTS/CTS and DSR/DTR handshaking signals are disabled by
default (via jumpers) (and, in worst case, also by additional inaccesible
hardwired connections, hidden underneath of the jumpers)

----

=== Cirkit Serial Interface ===
Used by [[Cirkit serial interface]] (for use with the included Prestel Link modem)):
FADFh - Cirkit - 8251 UART Data register
FBDFh - Cirkit - 8251 UART Status/Control register
TX clock source is fixed (19.2KHz), RX clock source can be selected via DTR bit (1200Hz or 19.2KHz).

== 8251 vs 8251A ==

The original '''8251''' seems to be very rare (there's no programming info found in the internet). The '''8251A''' is backwards compatible, but includes some additional features. The 8251A gives some details on the additional features, so one could eventually use the '''8251A''' datasheet to reconstruct the functionality of the original '''8251'''.

However, since the 8251 is so rare, it's rather doubtworthy that the Aleste or Circit actually uses that chips, probably they use 8251A chips.

* The Circit advert says 8251 (which is maybe meant to be an abbreviation for 8251A).
* Russian to Western part number translation tables say KR580WW51A is 8251 (probably an abbreviation for 8251A, too) (especially as the ending "A" in "KR580WW51A" implies that it is an 8251A).

Schneiderware Uni-PIO

2010-10-01T04:10:12Z

Nocash: /* Article */

The [[Schneiderware Uni-PIO]] is a general purpose I/O port with 48 input/output signals, published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port.

== I/O Ports ==

Default I/O Addresses are F8E8h-F8EFh, optionally a second or third Uni-PIO card can be jumpered to F8F0h-F8F7h and F8F8h-F8F8h, giving a total of 144 I/O lines when using three cards.

{|{{Prettytable|width: 700px; font-size: 2em;}}
|Address (default) || Address (alternate) || Usage
|-
|F8E8h || F8F0h,F8F8h || Schneiderware Uni-PIO [[8255 PPI chip]] #1 Port A ('''without''' pull-ups, with red LEDs)
|-
|F8E9h || F8F1h,F8F9h || Schneiderware Uni-PIO [[8255 PPI chip]] #1 Port B ('''with''' pull-ups and green LEDs)
|-
|F8EAh || F8F2h,F8FAh || Schneiderware Uni-PIO [[8255 PPI chip]] #1 Port C (lower 4bit '''without''' pull-ups and red LEDs, upper 4bit '''with''' pull-ups and green LEDs)
|-
|F8EBh || F8F3h,F8FBh || Schneiderware Uni-PIO [[8255 PPI chip]] #1 Control
|-
|F8ECh || F8F4h,F8FCh || Schneiderware Uni-PIO [[8255 PPI chip]] #2 Port A (without pull-ups or LEDs)
|-
|F8EDh || F8F5h,F8FDh || Schneiderware Uni-PIO [[8255 PPI chip]] #2 Port B (without pull-ups or LEDs)
|-
|F8EEh || F8F6h,F8FEh || Schneiderware Uni-PIO [[8255 PPI chip]] #2 Port C (without pull-ups or LEDs)
|-
|F8EFh || F8F7h,F8FFh || Schneiderware Uni-PIO [[8255 PPI chip]] #2 Control
|-
|}

'''Cautions''' - Port F8F0h-F8F3h were also used as alternate address of the [[Schneiderware Centronics Port]], recommended work-around is to modify the Centronics card. On the PCBs, two PPI #1 Port C signals are accidently exchanged with each other (wired to the wrong pins on the 50-pin connector, and to the wrong LEDs).

Schneiderware

Nocash:

The [[Schneiderware]] series consists of several DIY projects which have been released in german magazine [[CPC Schneider International]] published by [[DMV]]. The name "Schneiderware" was probably choosen due to its double meaning ("CPC Hardware" in computer language, or "specially fitted clothing" in german language). Aside from building the hardware on one's own, one could also order printed circuit boards, either fully assembled, or plain PCBs without components.

The various boards are having special connectors, intended to be mounted on the "Basisplatine" (some kind of a motherboard with [[ECB Bus]] sockets) which allows to connect up to five Schneiderware boards to the CPCs Expansion Port; with some small modifications one could also connect the boards directly to the Expansion Port (the motherboard is merely an Y-cable-like adaptor without electrical components, so one doesn't really need it).
