Yey, I Love Finding Photos Of Mainframes In Use From The Archives Of Colleges. This Is An IBM System/360

Yey, I love finding photos of mainframes in use from the archives of colleges. This is an IBM System/360 model 30. Their lower end of the System/360 range. Introduced in 1964 and shipped in 1965.

Initially this entire machine had the maximum memory of 64k. In the early ‘70s 3rd party manufacturers started to realize it was built to accommodate more (up to 128k, though just 32k upgrades cost near $40,000), so IBM offered options to upgrade the memory to 96k.

The 360 was created with the intent to be used with shops that had an IBM 1401 (introduced 1958). It could be configured with an optional emulator to run their existing software. Short sighted business then bought the machine configured with 16k as that was the 1401s maximum memory capacity, why would you need more, when the machine could be much much more capable at 64k. You could load DOS/360 to “partition” the machine for 2-3 concurrent jobs.

James Wilson super empathetic and incapable of making rational decisions when someone is in pain and he decided to specialize in treating terminally ill patients. No wonder House wants to study him like a bug

1968 Olivetti Valentine.

Interesting that 10 years on it was still recognized as being stylish, and now 60 years later, it’s eye-catching. Some things are timeless, to design something like that must give the artist an ever lasting high.

Or they could be using it as a joke. The man is writing a love letter. (Valentine - “I love you”)

(Also note they ended production in 1975).

Got any more VCF East photos?

You’ve likely already seen all the ones I had taken in your discord. All shot with a 50 mm, kind of square squeezed look. I go by a different name there though.
