Dunno, ask the experts at news://comp.os.cpm maybe?

(That link isn't linking properly due to forum limits, but you get the gist.)

I have found this nice in-browser emulator for the stuff:
https://www.pcjs.org/disks/pcx86/cpm/1.1b/

It could be interesting to make some fasmg macros for programming of this machine, but I'm afraid it is still far down the list of things I would like to make with fasmg.

And now I started thinking about running fasmg in the browser... Would Emscripten do? But that would require translation of fasmg sources to LLVM language... Anything that can directly emulate 386 instruction set should in fact suffice. Or, wait... what about writing x86 macros for fasmg that instead of opcodes generate JS source? Very Happy

Hello. I use the pce emulator. I made a cpmtools definition and this seems to work more or less for pimg hard drives:
Code:
diskdef pce-pimg # totsz=a28e00 # dir=8600 # direntrysz=0x20 # data=0x2800 # => maxdir = 2048d # blocksz=1000=4096d # => boottrk=dir/(seclen*sectrk) # => tracks=totsz/(seclen*sectrk) seclen 512 tracks 2592 sectrk 8 blocksize 4096 maxdir 2048 skew 0 boottrk 8 offset 2560 end
