Oh, stupid me... I cleaned up the junk pile a couple of months back
and not thinking threw out about 20 of these mfm critters, not thinking
they were much usable, any more.  I did save a couple of the 150mb
mfm things from the Sun3 crate, though.  They were Micropolis, if
memory is correct.  All the 20/30/40/60/80mb things I chucked.
Oh well.

On the ESDI drives, has anyone tried the IBM things from Model 60
and Model 80 machines?  They were 70/115/300mb drives, and are
quite common.  If they were usable, I have bunches of those that
have not yet been thrown out.  They are also quite numerous in
local surplus.
