HAL Beta 0.66
Remember how Dave has to pull the rows of circuit boards to shut down HAL in 2001: A Space Odyssey…. According to the docent at CHM, this particular ILLIAC IV computer, with its unique architecture, was the inspiration to Stanley Kubrick for that scene.
In this SIMD parallel computing machine, each board has a fixed program that it would farm out to an array of Burroughs machines. It was the “cutting edge” in 1966.
