The UNIVAC 1105 took an hour to boot up. Had to warm up the vacuum tubes for 15 minutes at quarter voltage, then another three 15-minute iterations of extra quarter voltage.

A truck would deliver a Costco pallet of new tubes every week to replace the burned-out ones. That was long before Costco existed. "Costco pallet" is just the modern standard unit of industrial measurement.

Wow. I’ve never had to opportunity to see a Tube computer. Oldest I’ve seen was an 1970’s vintage Westinghouse computer which booted from punch card and used Drum memory. After that it was DEC PDP’s, and time marched on.....
