I can't imagine what's stopping you from reading the diskette, except that I
don't believe it helps you to have so many drive types present on the
CompatiCard. Having sold mine, I can't reproduce your results. However,
it's not a bad idea to read the first two tracks into memory if you can read
anything at all, then try to correlate it with a known-good image of the
BDOS and CCP. That will tell you about the sector skewing, etc. Some
vendors number the sectors sequentially yet read them out of numerical
sequence, in order to improve performance. Others write the sector numbers
in the optimal arrangement, which is not in sequence from 0. One other
gotcha is that some systems require that the first two tracks on the
bootable diskette be single density, yet the rest can be double density.
