CP/M- and Amstrad-related stuff

Another page of vaguely CP/M-related stuff.

Local resources

• The PCW software interface specification from Amstrad. Definitive info on I/O port usage.
• My minimal notes from before the release of this document; also some info on the usage of the I/O space by some common peripherals.
• An (unofficial) pinout of the PCW expansion port.
• Some observations on the PCW boot sequence. (new)
• MDA and MDP specifications from Creative Technology and also some information on CUT and GRF files from me. A self-extracting archive (for CP/M) containing (an older version of) this information (with diagrams as a CUT file) is available for download.
• A page about Chaos Cottage BBS (UK-based, dialup).
• Information on Amstrad's intelligent file transfer protocol.

Links to other people's stuff

• John Elliott's CP/M resource. Details of BDOS and BIOS calls, GSX, the SCB, and the Amstrad CPC/PCW and Spectrum +3 extended BIOS (a viable alternative to getting hold of the now almost unobtainable book The Amstrad CP/M Plus by Clarke and Powys-Lybbe). Also a file archive containing numerous files unavailable elsewhere; various CP/M-related year 2000 fixes; an implementation of CP/M for the PcW16; and a PCW emulator for DOS, MacOS, and Unix.
• Unofficial CP/M page; among other things, contains such CP/M source, binaries, and documentation as can be found. (Current mirrors: 1 (ftp), 2, 3; old mirror)
• An archive of orphaned commercial software for CP/M. Also has the contents of the Walnut Creek CP/M CDROM.
• Richard Fairhurst had a PCW hardware reference.
• Ian Macdonald has a PCW page containing all sorts of links and other goodies (including the 8000 series circuit diagrams).
• Frank van Empel has many PCW DIY projects and various software.
• Official and unofficial Amstrad pages. Information and resources (setup discs etc) for all Amstrad computers including the PcW16 and old Amstrad PCs.
• Ansible Information produce a range of programs for writers for PCWs and PCs. There's also some freebie software available there, as well as all the old 'Langford' columns from 8000 Plus (and the new ones from PCW Today).
• Locoscript Software (now owned by SD Microsystems) have their PCW catalogue online.
• The magazine PCW Today had a site with news and stuff.
• Michael Haardt's cpmtools package to use CP/M filesystems from Unix.

Newsgroups

• comp.sys.amstrad.8bit is the newsgroup most relevant to CPCs, PCWs and such. Most of the discussion is about CPCs but people knowledgeable about most Amstrad machines (including PCWs) do read it. (FAQ main site; mirror.)
• comp.os.cpm is a newsgroup for more general CP/M discussion. (FAQ main site; old mirror.)
