Revision as of 09:48, 25 September 2010

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 in kit form.

The various boards are having special connectors, intended to be mounted on the "Basisplatine" (some kind of a motherboard with ECB (Europe Card 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 DIY projects can be reportedly found in following issues (as by now, the magazine pages don't seem to be scanned, so details about I/O ports are unknown):

Notes: The "Centronics" board is yet another 8bit Printer Port solution (but different than the joystick-signal based one that was released a few months earlier in the same magazine). The Real Time Clock is somewhat similar to the CPCI Real Time Clock released in a special issue of the same magazine, but not identical (the RTC chip has different pin-outs, and some of it's 4bit registers are working slightly different, the leap-year bits, for example).

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.
