Definitely sound like Acorn CPM disks.

Can you keep an eye out for the Acorn version 2.00 BIOS which
allows hard drive access? I've got the ROM image, but as mentioned
in an early message, without the system tracks with the BIOS code
in them, it's a bit of a dead end.

http://mdfs.net/Mirror/Image/AcornCPM for the Acorn CPM
distribution disks.

CPMFiler at http://mdfs.net/Software/CPM/Filer will pull files off
Acorn CPM, Amstrad AmsDOS, Amstrad CPM and Torch CPN disks and
disk images. COPY CPM:*.* BBC: pulls everthing off in one go. I'm
currently tweeking it to access physical disks on RISC OS, as I
have done with SJFiler.
 
I'm working on how to do low level disk access on Windows, but the
easier route at the moment is to image the disk, then extract from
the image.

Careful! The CPMDISC file is a dummy file only on side 0 to
"partition" the disk. If you just copy that, you end up losing the
part of the BIOS that is stored in the DFS catalog, and all the
contents of side 1.
