Does that really work? I thought a lot of the half-height drives
used the same stepper for 40 or 80 track, and the drive circuitry
arranged for double-stepping on the 40 track models. Or maybe I'm
confused again.

Anyhow, you'll get more than 40 (or 80) since there is room for the
head to go out another track or two, but that's admittedly nitpicking.
