I just remembered something I hadn't thought of yesterday:

While I was a University student, my old high school bought a third-hand
IBM mainframe, as an on-site student timeshare system. A 4341.

Even though it was an IBM system, when a power failure caused the disk
drive (a 3330, or some such; I remember quite well what the thing looked
like) to jam in "emergency head retract," the tech who came out un-jam the
drive was from CDC.

Anybody remember removable pack hard drives? The kind where you screwed in
a pack cover, lifted the pack out, and put it on a sort of plate? One of
those pack covers might make a cute cake cover for a computer geek.  ;-)
