The early Micropolis 48 tpi drives (1015 Mod I) were spec-ed at 35 tracks.
The 100 TPI models (mod II) were 77 tracks.
Later drives included both 100 TPI and 96 TPI (e.g. 1115-5 and -6). For
a 5.25" drive, a beast of one. No wonder they quit making floppy drives.
Tandon was pretty sloppy with their labeling. I've got a TM-100-4M
that's identified as such on the body label, but the door latch handle
has a "96 tpi" sticker. Whatthehell, a bezel's a bezel, right?
