In the last video we got a first look at the Heathkit H8 Computer, that I acquired at the Vintage Computer Federation’s VCF West event, along with its peripherals in the form of the H9 Terminal, and H17 Dual-disk Drive. Now it’s time to see if we can get this classic 1970s vintage computer running. Repairs will be necessary.
