The [[Schneiderware]] series consists of several DIY projects which have been released 1986-1987 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 designer 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).
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):* [[CPC Schneider International]] 06/1986, Page 062-067, Schneiderware Introduction|Schneiderware #1 Introduction (Theory)]]* [[CPC Schneider International]] 07/1986, Page 060-067, Schneiderware Basisplatine|Schneiderware #2 2a Basisplatine (Motherboard) & ]]* [[Schneiderware Centronics Port|Schneiderware #2b Centronics (Printer Port)]]* [[CPC Schneider International]] 08Schneiderware V/1986, Page 070-077, 24 Interface|Schneiderware #3 V/24 (RS232 Interface)]]* [[CPC Schneider International]] 09/1986, Page 078-083, Schneiderware Power Supply|Schneiderware #4 Netzteil (Power Supply)]]* [[CPC Schneider International]] 10/1986, Page 078-085, Schneiderware Real Time Clock|Schneiderware #5 Echtzeituhr (Real Time Clock)]]* [[CPC Schneider International]] 12/1986, Page 124Schneiderware Uni-130, PIO|Schneiderware #6 Uni-PIO (48 I/O lines)* [[CPC Schneider International]] 01/1987, Page 144, Schneiderware Advert* [[CPC Schneider International]] 02/1987, Page ??-??, Schneiderware Analog Converter|Schneiderware #7 MIDI Interface Analog Converter (not part of the Schneiderware series8 analog inputs, 2 analog outputs)* [[CPC Schneider International]] 03/1987, Page 032-045, Schneiderware #7 A/D and D/A converter* [[CPC Schneider International]] 04/1987, Page 026-034, Schneiderware Pseudo ROM|Schneiderware #8 Eprom/RAM Pseudo ROM (SRAM and EPROM and battery-backed SRAM; both mapped as expansion ROM)* [[CPC Schneider International]] 05/1987, Page 032-034, Schneiderware #8 Eprom/RAM (Notes/Corrections)* [[CPC Schneider International]] 06/1987, Page 122-131, Schneiderware EPROM Burner|Schneiderware #9 Eprommer (EPROM Burner)* [[CPC Schneider International]] 11/1987, Page 097-099, Schneiderware Nachlese (Notes)Notes: The "Centronics" board is yet another [[8bit Printer Ports|8bit Printer Port]] solution (but different than the [[CPCI 8bit Printer Mod|joystick-signal based one]] that was released a few months earlier in the same magazine). The Real Time Clock is somewhat similar to the [[Real Time Clock|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 A summary of the I/O addresses FBE1-FBE3)ports, '''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 Schematics, Photos, and all scanned articles can be no Centronics and V/24 drivers included in databoxes.found here:* [[Schneiderware Summary]]
== I'''Note''' - Along with the Schneiderware series, there has been also a "[[CPC Schneider International]] 02/O Ports ==1987, Page ??-??, MIDI Interface" (advertised together with the Schneiderware PCBs, but not part of the Schneiderware series).
