Salt Lake City had something similar, Raelco - Ray’s Electronic Company I think. I spent so much time in there they offered me a job. It burned down several years ago.
Following on from my story elsewhere about working for HGST (Western Digital), visiting HQ in San Jose from the UK and making it to Halted a couple of times...
...then WD acquired Sandisk and I found myself in Utah for tech training, and made a trip to Raelco.
I used to bicycle down from the top of Bernal Rd. as it is very steep. The IBM Bernal (/Almaden?) campus is enormous, with an indoor golf cart for moving people around. I was there c. 1995 for a dark matter conference while I was still in high school (and I looked about 12).
it was packed, and that was just the front. If you got wire, you’d head to the back, and that was also packed. Maybe not a huge surprise it burned down. BUT, tons and tons of milspec parts.
Salt Lake Instrument was another place, but I only got to visit once after the guy had mostly retired. Tons and tons and tons of vacuum tubes
Tons of surplus from L3, Hill AFB, ATK, etc…
