No vacuum tube questions.

Fantastic deep dive as always, thanks for doing such stellar work!

On that note, any chance we might get a teardown/history of Cray architectures in the future? Specifically the Cray-1 and 2?

To throw a more serious challenge your way: How about a write-up on the original Frank Rosenblatt Perceptron? I know finding an original Mark-1 part would be close to impossible but it blows my mind that they were successfully doing real-time visual classification in 1957 with an electro-mechanical machine (potentiometers and motors) using a 20x20 "video" feed with some learning algorithm that was not based on backprop.
