When I was a computer (Data Systems) Tech — late '60's, aboard the USS Ranger (CVA-61), in the IOIC/flight ops secured space, of the Operations Dept — the lead-lined, 642-alpha and bravo Univacs we worked on, were 7' tall, 5' wide, x3' deep. Chill-water cooled, with 30-bit registers, and hard-wired, iron-core matrix memories (one each). They clocked in mega-cycles! And the bravo was a computer assisted, 'cleaned-up' version of the alpha — mainly to do with redundant memory addressing logic — and could do square roots. (can you imagine!)
