Was there ever a half-height 100 tpi floppy drive?
I've never seen
one.
I think there must have been. Didn;t the Commodore 8050 use 100tpi
drives? In which case the 8250LP ('Low Profile') and I guess the PET
8296D (Intenral drives, basically an 8296 and 8250LP built into one case)
must have used half-height 100tpi drives.
