⇡CP/M

The Ampro Little Board was a very simple and cheap Z80-based computer from 1984, which ran CP/M. It was, in fact, a single PCB which you could mount on the bottom of a 5.25” drive.

All about the Ampro Little Board

It stored either 400kB on a double-sided 40-track drive or 800kB on a double-sided 80 track drive. The disk format it used was a slightly quirky variation of the standard MFM IBM scheme — sector numbering starts at 17 rather than 1 (or Acorn’s 0). FluxEngine supports this.

FluxEngine has direct filesystem support for these disks, or you can pass the disk images into cpmtools:

$ cpmls -f ampdsdd ampro.img
0:
-a60014.e
amprodsk.com
bitchk.doc
bitchk.mac
cpmmac.mac
dir.com
himem.doc
himem.mac
kaydiag.lbr
kayinfo.lbr
...etc...

⇡Options
