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.....
We also had an IBM 1620 with maybe 4K of magnetic core memory. Each single core had two wires running through it. Had to pulse both wires to trigger a change state in the core from zero to one & back.
The 6600 at LMSC (formerly LMSD Let's Move Some Desks) had a big kachunka 80-column chain-&-gear-driven line printer. The printing batch job before [genius!] Ralph Gorin at SAIL wrote a spooler (simultaneous peripheral online output layer) ran all night, printing out Top Secret data.
The management spooks insisted that a heavy opaque shroud be thrown over the printer to prevent any non-cleared personnel from peeking at the sensitive info. Took ten months to acquire that level of security clearance, so the clearance-pending grunts they hired to work the AM shift regularly spent the morning digging compacted paper shreds out of the heavy printer gears. Your tax $ at work.
You might enjoy strolling through the Computer History Museum in Mountain View, CA. Some of it’s a dumping ground for beloved but hopelessly antique machine artifacts. There’s a rogues gallery of portraits along a long wall. On my first visit, I was amused to recognize almost every one as a former Professor, employer, or colleague.
