If you can get TeleDisk files of them, send me a couple of samples
and I'll work the 22Disk stuff out for you. After we did 22Disk 1.x,
we ran into a bunch of formats with bizarre formatting (dissimilar
sector sizes, tracks distributed alternately from the middle of the
diskette, varying sector numbering from track to track, etc.) We
built a 22Disk 2.0 to handle them, but it requires that the format
definitions be compiled in, rather than as a text file. On the other
hand, it caches directory tracks and works out the fastest way to
read a track (I/O is track buffered). So there may be some hope
there if things are really strange.
