While the upgrade was partially successful, a deep dive into the Socket 7 and Super Socket 7 documentation helped him realize the need for a pullup resistor on a strategic clocking pin.
The key difference between the two was that Socket 7 had an extra pin for dual split rail voltage versus Socket 5's single voltage. Super Socket 7 didn't arrive until 1998 and served as a stopgap ...
