OK I know it's not Apple and it's not exactly fully functional but a nice envelope came through the letterbox with a little white box containing...
An unused part for a Univac machine!
Sadly it's not from the Univac 1 (i.e. 1950's) but is more likely to come from the mid-70's but it's still amazingly retro. No chips but about 20 surface mounted components (resistors, a transistor (the big three legged kind) and a couple of diodes) on a very primitive circuit board. It's still in its original blue ploystyrene holder and original white cardboard sleeve (proudly boasting the company name and a dazzling array of undecypherable part numbers)
No idea what the hell it does, what it's for or whether it works (amazingly I don't have a mainframe to test it on 😉 )

Post pics. With some of the electronics folks on this board, I bet we can guess at its intended purpose with some degree of accuracy!

Not even enough circuitry there for a flip flop.

Oh man, those solder traces on the back are amazing!

Are those resistor colour bands hand painted???

That's an outcome of then resistor fabrication technology. Note, however, that only four of the resistors are of four-band precision (gold). The others argue that some precise voltage-division is going on. And the board beats the hell out of four-layer boards for ease of tracing the circuitry ...
