But the general code to do a raw read of a disk is pretty boiler-plate.
 What I did way back when was to write a simple program to read the entire
disk (raw) and dump in HEX out a serial port. I then captured that output
on Linux, after which it was a fairly simple matter to turn that HEX dump
into a binary file that cpmtools can use (or potentially anything like an
IMD image). I don't know if I can locate any of that (from 25 years ago),
but it is not too difficult to reconstruct.
 

I recall doing something similar in ages past.  I had an Osborne 01 running CPM 2.2 and I essentially did a track by track read (like the included COPY program)and fed the binary to XMODEM (I had the source code for that) that was then received by my PC running Procomm.  Didn't need to bother with hex as an intermediate step.
I still have the Osborne, but now it has a Gotek flash drive in place of drive B. And of course a recapped power supply.
