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.
