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.
|
|

|
|
|
|
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](http://www.moria.de/~michael/cpmtools/):
|
|
|
|
```
|
|
$ cpmls -f ampdsdd ampro.img
|
