The [[Schneiderware Centronics Port]] is an external [[8bit Printer Ports\|8bit Printer Port]], 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 ~~various boards are having special connectors,~~ intended to be ~~mounted on~~ the ~~"Basisplatine" (some kind of a motherboard with~~ [[~~ECB Bus~~]] ~~sockets) which allows to connect up to five Schneiderware boards to the CPCs Expansion Port; with some small modifications one~~ could also ~~connect the boards~~ directly to the Expansion Port ~~(the motherboard is merely an Y-cable-like adaptor without electrical components, so one doesn't really need it)~~.		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.

An alternate I/O Address is jumper select-able (intended to allow to connect two Centronics cards to the computer), the alternate address was originally defined as F8F0h-F8F3h, but the later [[Schneiderware Uni-PIO\|Schneiderware #6 Uni-PIO]] project did accidently use that addresses, too. In result, it was somewhat suggested (or silently implied) to change the secondary Centronics address to F8E4h-F8E7h.

The [[Schneiderware]] series consists of several DIY projects which have been released in german magazine [[CPC Schneider International]] published by [[DMV]]. The name "Schneiderware" was probably choosen due to its double meaning ("CPC Hardware" in computer language, or "specially fitted clothing" in german language). Aside from building the hardware on one's own, one could also order printed circuit boards, either fully assembled, or plain PCBs without components.

The various boards are having special connectors, intended to be mounted on the "Basisplatine" (some kind of a motherboard with [[ECB Bus]] sockets) which allows to connect up to five Schneiderware boards to the CPCs Expansion Port; with some small modifications one could also connect the boards directly to the Expansion Port (the motherboard is merely an Y-cable-like adaptor without electrical components, so one doesn't really need it).
