I seem to remember that it was 77 tracks of 26 sectors (or some other
fairly odd numbers). Never had one, but CP/M has some built in tables
for these. That's were those ugly 128 byte records come from that almost
everybody else had to block/deblock in their BIOS, wasting precious space.

Just looked into wikipedia: it was really 77x26x128. Equivalent to 2002
punch cards (2000 was a common box size for those, it seems).
