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 ampro400
You should end up with an ampro.img which is 409600. If you have a
double-sided disk, use ampro800, which will give you a file819200 bytes long.
These is an alias for fluxengine read ibm with preconfigured parameters. You
can pass this straight into cpmtools:
$ cpmls -f ampdsdd ampro.img
