View source for Schneiderware Analog Converter

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).
