I think I found the schematic.
Many of the boards for coin-op games looked like that even new from that era. I fixed a handful of games in the shop by simply reflowing all of the low-quality solder joints.
Nothing like hand layout.
No, I mean it probably gets really hot.
Looks like the PC board on a device I had repaired three times. Since it was a safety accessory I finally replaced it cuz I didn’t want to be stuck with a broken device in the time of need.
Looks like a power supply.
You should see the CPU board in early Stern pinball machines - real trippy.
Backside of the P314 deflection board in a Wells-Gardner 6100. Looks like there have been a lot of hands in here over the years. Thick-fingered hands.
People say I'm hard to shop for, but for the record, I can give a good home to an extra WG-6100 or two. These things are unobtainium now.

These are my people.
Was there a name on the card?
Here's the reverse side:
Please don’t tell me this means Tempest is a paperweight again.
At least they used a hand-drawn PCB. The prior choice would have been point to point soldering
