Anyone recognise these pluggable PCBs?

Love the rivet style vias :)

Wonder what happened to the LED driver board, where it seems to be missing a bit :-DD

It's a nice clean cut, with an appropriate bodge wire on the underside to make up for the severed track!

AndyBeez:
Certainly a modular system made from robust fiberglass PCBs. A range of date codes and component styles suggests these were bricked and fixed over a couple of decades. The ground returns look standarised on the back. The pcb traces are an example of hand positioned sticky tape masking. The rivets are unique.

btw, before any Pi bunny suggests otherwise, these are not parts from Steve Wozniaks prototype Apple computer, and therefore not worth a fortune at Sotherbys... or are they? ???

Maybe some of his earlier work :-DD

A bit of a shame the cut on the LED driver is clean and not like the Apple 1 board that is up for sale now :palm:

The IC sockets look awfully similar to those in the prototype, including some with the white 'feet' that I've never seen before.

I have about 100 of these boards... I could be sitting on a small fortune! 😊
