Deusche Fotothek has some photographs taken in a data centre in East Germany's Dresden (DDR) 1975.

Look at how they are dressed - probably a bit cold in that room I'm thinking. My mom worked at General Electric in the 1970's, and told me that the ladies who worked in the computer building were always wearing sweaters to fight the cold, as GE kept the temperature at 60 degrees.

I had to convert that. Fahrenheit says little to me (I know 90 is 'hot').

Sixty degrees Fahrenheit equals 15.55 degrees Celsius.

Ah yes the good old days of disk packs. From the days when the drive platters were separate units from the drive head & controller, which was the size of a washing machine. You could eject the platters and take them with you. Today's drives have all that integrated.

IBM 3340 "Winchester" was something halfway between fixed and removable storage technology.

"The medium is a removable disk module that has the mechanics with the read/write head built-in, in contrast to the former removable disk packs. This allowed a remarkable increase in capacity because tolerances of head adjustments didn't have any influences between different drives and disk packs any more."
