It was an NCR 9050 mini, with 658 disk drives. 15 inch removable packs but I don't remember how many platters on them. IIRC they were actually manufactured by CDC.

The BUNCH machine's I'm familiar with were somewhat earlier, and didn't have removable disks. What machine and drive was that? FWIW, I know something about all five but have only used CDC and UNIVAC, plus a dwarf not part of the BUNCH. -- Shmuel (Seymour J.)

No tape on it so backups were removable disk to removable disk. Director was too cheap to spring for tape drives/media and also decided we didn't need to back up load modules because "if we lose one we can just recompile it". Part of a bigger disaster was that we lost the disk containing all of our load modules. Took a week to get the computer back up and running and all our programs recompiled. Did I mention this was a hospital?

My very first programming job, the tape librarian quit. (Remember tape libraries and librarians and manual tape management?). Our boss was too cheap to hire a replacement with any overlap in employment dates. So the new woman started with no tape librarian experience. Everything seemed to be going well for a couple of weeks ... until it turned out that if she got a scratch request and could not find the volume -- perhaps it was lying on someone's desk or something like that -- she would scratch the closest match she *could* find. For example, if the scratch request was for VOLSER 274382 and she couldn't find it, she might scratch 274383 because it was the closest match she could find. Just trying to do the best job she could ...
