Disk: Ampro Little Board

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.

Reading discs

Just do:

fluxengine read ampro

You should end up with an ampro.img which is 409600 or 819200 bytes long. This is an alias for fluxengine read ibm with preconfigured parameters. You can pass this straight into cpmtools:

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

kaydiag.lbr
kayinfo.lbr
...etc...
