I can't even get IMDU to even build.  It appears to assume it's being run on MS-DOS, on bare metal.

I got cmios9 working after a fashion, but not before I'd written my own .wav extractor.

If you look at the end of cmidisk.c you can uncomment a bit that will spit out the whole extracted image.  Note that although my crude IMD routine does unpack different disk sectors in the right order, it ignores head and track mapping blocks (just skips over them) and assumes that the cylinder and head are written in the correct order.  If you find any disks that do not provide the same output as IMDU.COM (check with md5sum) please file a bug on github.
