a 40/80 switchable, and a rather better device than the BASF. I've got one
here, with some extra switches so it can emulate the peculiarities of an
RX50.
What I like was the double drive that Canon made in a 2/3 factor. 2/3 the
height of a "regular" drive, but with 2 slots. (Maybe I'll sell it at
VCF) They made several variants of it, including models that had two
stepper motors, and ones with one stepper (both drives are on the same
track).
Quick simple puzzle: why would a drive that steps both disks at the same
time be significantly SLOWER when DISKCOPY'ing a disk than using separate
drives?
Hint: MUCH faster when copying if you write software specifically for it.
