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).
