    I had that exact breadboard system back in the early '90s when my high school gave it to me as surplus equipment. Unfortunately I lost it along with many other electronic and old computer systems back in 2013. Mine had various wiring and component failures too, but it still worked as a breadboard. I think one of the voltage rails worked rails, but didn't have the technical expertise at the time to fix the rest of it. It's great to see one of these systems featured and being put to good use!!

    Back in the day, it was not uncommon to have a number of new IC's that were defective out of the box. You could use something like this to test a device you expected to be bad. On a board with 20 or 30 dips, bad parts, open vias, data sheet erata and incorrect pcb routing were the norm. It was so bad for a while we sent all our IC orders out to be burned in and re-tested. Now it's very rare to see a bad part, now we are plagued with counterfeits.

    Oh no; sticky shafts! I recently had three of them in an old tube radio (volume, treble and plate capacitor). I found out that heating up the shaft with a soldering iron makes the old, sticky lubricant at least fluid enough to move the axles. Removing and cleaning them is of course the easiest and best option. I had to alternately put lighter fluid and oil into the friction bearing because it was not removeable. Did work out fine. Thanks for the ride again! :)
