1974 Brain Box saves the day.

I find it interesting how this old stock mopar board has hand written component numbers, probably from the '70s.

Kind of makes you wonder what the manufacturing process was at the time. They did work well though.

Maybe some of this numbering and lettering of the components means something to the better educated electronics people on our site here ?
