Here’s a shot of a digital clock (I think!) or maybe its a 7-digit counter, I don’t recall anymore, I found it in a box in the basement while looking for something else.
555 with RC & trim pot for clock source, some 7404/7400/7408 across the bottom
2nd row is 6 74163s and a 74160, so 28 bits of synchronous counter
3rd row, a 74H74 and parts likely cannibalized for something else (they are wired up)
4th row is 7447’s driving the digits, which are HP 5082-7730s.
Things that look like burn marks are epoxy, apparently I reused this piece of non-copper clad perfboard.
Back is mix of wirewrap, caps soldered on the sockets after wiring, and point to point soldering for the resisters to the LED leads (be tough to reuse those now!).
Ah, the good old days - parts are dated coded 1978, 1978, so was probably built when I was co-op student after college sophomore year.
