82901A and the
HP 9121D now work great. Quite low capacity (270k?) due to
the weird LIF formatting, formats 35 tracks but uses only 33, out of the
40. I wonder why.
Partially because the original 5.25" drives (Shugart SA400)
were 35 track (#0
- #34), not 40.
I don't even remember, . . .
Does LIF also reserve some space for substitution for bad sectors?
(there were a higher percentage in those days)
