CP/M-86 & MS-DOS Cross Development Environment

- trn 4mo agoWe also have a new CP/M-86 emulator at https://github.com/johnsonjh/emu2-cpm86 https://github.com/johnsonjh/emu2-cpm86
- stevekemp 4mo agoTake a look here for some other tools: https://github.com/skx/cpm-dist https://github.com/skx/cpm-dist I found the compiler collection here useful too: https://github.com/davidly/cpm_compilers https://github.com/davidly/cpm_compilers Though I guess some of these things won't run under the linked emulator, because they use SUBMIT and require more than a single-executable to be run. (That's the reason why my own emulator used the CCP/"shell" rather than just limiting itself to running FOO.COM)
- rwmj 4mo agoI wonder if anyone used CP/M-86 back in the day? I used CP/M 2.2 and 3.x on Z80 pretty extensively. But on 8088/8086 it was MS-DOS everywhere. Were there niche CP/M-86 apps or use cases?
- peterfirefly 4mo agoThey used it at my high school in Denmark. It was easy to share hard disks across many machines and the ability to multitask was also very nice. The office people could switch between word processing and calendar software easily, for example.
- Zardoz84 4mo agoDR-DOS was CP/M-86
- icedchai 4mo agoDR-DOS was an MS-DOS compatible OS and did not run CP/M apps.
- tengwar2 4mo agoDR-DOS (https://en.wikipedia.org/wiki/DR-DOS https://en.wikipedia.org/wiki/DR-DOS) was reasonably popular, and was a derivative of CP/M-86. I never saw the original OS in the wild, though.
- kjs3 4mo agoI knew some shops that went CP/M-86 because they were big CP/M-80 shops and thought the price difference was worth a presumably lower conversion and training cost. Didn't last long since MS-DOS ate the software world, which is all that mattered.
- andrewshadura 4mo agoV20 is an interesting CPU. A 8086 compatible with support for some instructions of 80186 and 80286, some custom instructions, an 8080 emulation mode… The datasheet describes the instructions using a non-Intel notation that looks very unusual. https://en.wikipedia.org/wiki/NEC_V20 https://en.wikipedia.org/wiki/NEC_V20
- Floppyrom 4mo agoWhat was the peak moment for CP/M? Wordstar?
- tengwar2 4mo agoI'd say the last versions of CP/M for the Z80 - particularly on the Amstrad CPC128, PCW256 and PCW256. We had a whole lab using PCWs as standard equipment, including one sitting at a 3000V DC offset in a perspex cage (controlling part of a C14 accelerator). CP/M 3.0 did bank-switched memory, so the graphics were switched out and you could copy the user-space utilities in to a RAM disk on startup. It was reasonably easy to write RSXs (analogous to TSRs on MS/DOS), which can be handy on a single-tasking OS.
- rigonkulous 4mo agoGEM.
- whobre 4mo agoGEM ran on MSDOS and GEMDOS
- rigonkulous 4mo agoGEM had a CP/M compatibility mode.
- nickdothutton 4mo agoSupercalc2, Maxam2, dBASE II. You could do a lot with CP/M software, especially if you had access to a hard drive which would eliminate the "insert floppy disk X into drive Y" tedium.
- kjs3 4mo agoAdd Turbo Pascal.
