An HP150-II will use the 9121 signle-sided drive, where it formats it to
70 cylinders (and probably gives you 66 of them). I think an HP150 can
use the later double-sided drives like the 9122 (and will format them to
77 cylinders), but it may need a BIOS ROM upgrade amd/or a later version
of MS-DOS.

I saw multiple DIFFERENT upper limits (66 and 70)
on discs (HP refused
to call them "disks") that were supposedly the same format.
Indeed, the HP150 Series II floppies used 77 cylinders for data.
