Micropolis was one of the only ones to use a helical

for a 5.25" floppy. VERY SLOW. They also made a 100TPI (not 96) drive.
Wasn't Micropolis' drive a 77 track thing?
Starting with the MPI B51, most drives went to a split band positioner.
In addition to the spiral groove positioner, the SA400 was 35 track,
whereas all others that followed were 40 track.
I have both SA400 and MPI B51s. They are compatible.
But this all begs the question of what systems had what drives in them?
I know that most early systems used SA400s (35 track), and that the original
IBM PC used Tandon 100s (40 tracks). But what of the others in between? I may
have asked this already, but does anyone have a table or something similar?
