Getting a decent frame buffer in those days was a significant challenge, though. It was like "Hey, the University of Qwghlm just got a 512x512x24 display, let's go apply to grad school there!"
About 20 years ago I was helping a guy design a vector unit for a new CPU. As I was writing the simulations, I began to appreciate Cray's 70s era designs, and the stuff that we manage to stuff into a few square millimeters of silicon these days. The future is here.
