The other common sets with double sided boards were
mid 70's Toshibas. They put a stake through the board instead
of gripplets. Both the mother board & modules had them &
lots of intermitants showed up in a few years. They changed
to hard wire in a short time. RCA had some but they used plate through
& only problem I seen was a few burned. Also Maggy tuner
pkgs on C1 & C2 chassii IIRC. I know there were others but cant
remember now
