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).

Along with the Schneiderware series, there has been also a "CPC Schneider International 02/1987, Page ??-??, 7 MIDI Interface" (advertised together with the Schneiderware PCBs, but not part of the Schneiderware series).
Databoxes: UHR8000 RTC-RAM-driver in 10-1986 (hex listing, plus Hisoft Devpac source code) (caution this version uses incorrect I/O addresses FBE1-FBE3), UHRC000X RTC-ROM-driver in 4-1987 (this version uses correct I/O addresses FBE2-FBE4). Uni-PIO examples in 12-1986 (=only a few basic lines). There seem to be no Centronics and V/24 drivers included in databoxes.
