Subject: Re: Original Digital Research CP/M 2.2 disk format.

With a copy of AnaDisk you should be able to determine whether it is readable
on a PC, and the characteristics of the format - sector size, interleave, 
sector numbering, etc.

With that information, you should be able to 'build' a custom format identity
for 22Disk, and thus read the disk.

An alternative is to send the disk to Sydex, along with the 22Disk registration
fee, and they will 'build' the format identity for you.
