The Univac I worked on in the Navy in 1976 had 32K of core memory. The RD-273 disk drive was four 12-inch, 20-surface, disk packs with hydraulic actuators. It was the size of two 'fridges. But the coolest thing was the Xynetics flatbed plotter. The "head" that held the plotter's pens had no mechanical linkage. It was driven electromagnetically.
