View source for Schneiderware EPROM Burner

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]].
