After soaking in water for four days, I tried using a little steam cleaner (Euro-Pro).
It's working, but slow. I got about 1/2 of a mound cleaned off in an hour. A mound
that was on a flat surface (the disk drive chassis) actually slid off after undermining it
with the steam! Looks like I'll be able to save the drives.
Does anyone have a manual / schematics for the Calcomp drives?
Models 140 and 142.
Thanks,
Bob
