Since I finally upgraded to Socket 370 I also took the liberty of upgrading my sisters system which was also a Socket 7 which I owned previously.
It supports Intel Pentium, Cyrix 6X86, AMD5k86, AMD K5 processors at bus speeds of 50mz-66mz but possibly 75mz. It uses 72pin EDO RAM and takes AT power supply. It has 4 ram slots, 3 PCI slots and 4 ISA Slots.
All the Cpu's used on this board are Socket 7 and the maximum bus speed that I know you can obtain is 233mz at 66mz multipliers of 1.5, 2, 2.5 and 3 for processors such as the Pentium, Pentium MMX, AMD K5 or K6 and Cyrix 586 or 686 processors. As for higher speeds than 66mz bus you would be looking for a Super 7 series.
The ram used is the rarelly obtainable 72pin EDO ram and I also have a Pentium 100 if you don't have a cpu. This is ideal for older systems.
