And, of course, I already had a small stack of TM100-1 drives in 1981, 
when I needed some for 5150 PC.

drive for my TRS80s.
96tpi, admittedly took a little longer to be available, but it 
seemed an obvious better choice than 100tpi, just for the [admittedly 
flawed] interchange possibility.  Many years later, in a pile of TM100-4 
drives, I got a TM100-4M, even though I could never find one when I wanted
