Ok, now that I can take count, I got a PCB with:
6 whole socketed CDIP D27128 16k x 8b UV erasable PROMs
10 soldered TC5516 2k x 8b SRAM
1 soldered 74HCT138 3-8 demultiplexers
2 soldered 74HCT139 dual 2-4 demultiplexers

There's also maybe 20 of the potentiometers, about 50 BA4560 dual op-amps, three varicaps (the square ~plastic 10-150pF ones with like 4 extra mini varicaps on top).
Then there's ~10 of these black boxes, some with 10 pins, some with 14 (the extra 4 are just chassis mounting pins). Looks like theres two MELF packages in the bottom, and two adjustable screws on top. They have the writing "184006" on one line and "E282" on the second. Pic related. Any clues?

Oh and most of the tech shit in >>1942462 is for TV broadcasting stuff, hence the TV camera, TV-specialist oscilloscope, TV screen bank for mixing, control racks, even a background music looping tape. A handful of vacuum tubes too. While I could buy one of those just for the curiosity or the parts (the scope is $80), it would probably be a waste of space.
