The Rana1000 disk drive made for Apple and Atari 8bits also had no track
zero sensor. It used a simple timeing scheme to ensure the head HAS to be
at track zero by now..... The knocked themselves out of alignment

I think Commodore 8-bit drives like the 1541 also had no zero sensor

The Atari 8-bit drives all had them that I can recall, Percom, Indus,
Trak, etc.
