Bugs in computer hardware (real ones) steam works

[Bob Rosenbloom]

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
