And the disk drives on that 360 had hydraulic actuators to move the heads. Was that the 2301 or 2311 disk, or something else? Where I was in IBM Poughkeepsie we kept our programs on removable disks of somewhere around 16 in. in diameter. I don't remember the capacity but it was in MB. At the end of the line of disk drives sat our 029 card punch. I spent way too many hours at that punch because my fingers were so inept. There was no backspace 'cause you can't unpunch holes.
We used a card based program to modify the code that accumulated on our personal disk as ISAM data sets. I set that up for my department after dropping and bursting open a very long portable card carrier (of mostly unsequenced cards) that was used before my 1967 "innovation." :-)
What shocks me at the moment is the incredibly clear 50 year old mental map and images I have of that machine room and the computers in it. A 360 model 50 that I primarily used. Beside that a model 40, down the isle a model 67, behind that a 7094 and further on a big ol' model 85. Across the hall a honking model 91. No 1401's in that room, however, but lots of 1403 printers.
