Super Socket 7 was an extension to Socket 7 which AMD K6-2 and K6-III CPUs used. It raised the front side bus speed to 100Mhz, and was backwards compatible with Socket 7 (used by Intel CPUs) and Socket 5 (in some cases). Other CPUs from Cyrix, IDT and Rise used Super Socket 7 as well.
I only have one example of a Super Socket 7 CPU at this time.
AMD AMD-K6-2/500AFX 500Mhz
