If it is for an IBM 2311 or 3330, dig fast.
Not IBM. Control Data, maybe? For some reason "Model 40" comes to
mind. It's a weird format, very large pages, 11 inches is the _shorter_
dimension.
Singer? ISTR that Singer had a model 40 drive (14 in disk pack) in their
system 10. Possibly using rotary transformer servo like Diablo Systems...
No, these were single-platter setups, typically one fixed and one removable.
I had one repair to look at that was basically a "Wang Word Processing
System" or somesuch, and there was a mini that I tried (not very
successfully) to deal with called a "GRI" -- the company was out of business
when I came into the picture in 1985, and they had a guy who would come in
from out of state from time to time to tweak things. I
still remember having
to find exactly 5.06 volts across one specific capacitor to
make things work
right. That had four racks, and drives in two of them, and it was a much
nicer setup than the one I'd encountered besides, which was a "pedestal" of
some sort, took two of us to move it. The rack-mounted units in the mini
were in drawers that you could pull out, and I think tilt down at full
extension.
I remember one time they started having all sorts of trouble with that
machine, and it turned out that the temp in the machine room had gone up by a
few degrees, due to a bad belt on the outside portion of the a/c that was
slipping. Fussy, that thing was!
