Seymour Cray's only surviving recorded talk, introducing the Cray-1 supercomputer in 1976. He describes the machine's design, including its vector architecture and cooling through the frame.

Cited as a rare first-hand account from Cray, loved for details like the aluminum machining invented to carry Freon through the frame.

Cray himself. Here's a talk about designing it. My favorite part is his description of the aluminum machining they had to invent in order to move the freon through the frame to keep the machine from melting. It's a great talk. ▶ this video

It reminds me of Seymour Cray's solution. Well, series of solutions, to run Freon directly through the frame of the Cray-1. ▶ this video
