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.



CPC WIKI POWER SUPPLY

POWER SUPPLY - (DMV 1986)
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).

CPC WIKI REAL TIME CLOCK

REAL TIME CLOCK - (DMV 1986)
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.
The Schneiderware Real Time Clock is somewhat similar to the 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.

UNI PIO- (DMV 1986)
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.

SCHNEIDERWARE #7

 


CPC WIKI ANALOG
WANDLER/CONVERTOR

AD/DA - (DMV 1987) - WANDLER / CONVERTOR
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).

CPC WIKI PSEUDO ROM

PSEUDO ROM - (DMV 1986)
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.

CPC WIKI EPROMBURNER

EPROMBURNER - (DMV 1987)
The 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 ROM/EPROM board
