Got me beat ,, I used to be a storage admin ,, had a boatload of 3330-1 and 3330-2’s AND a 3850 mass storage system ,, thought I was in heaven when 3350’s came out in quantity... unfortunately when IBM had a minor 3380 problem and shut down production for a while we had to buy those hideous StorageTEK 3350 copies that had head crashes after 3 months of use..
When our department finally got permission to acquire its own data processing computer, we got a 360/22 (a stripped-down reconditioned 360/30). We got Telex tape drives and 2311-equivalent disks. And a real IBM 1403 printer.
I wrote my first (and undoubtedly only) PL/I program on that Beest.
