    Super Socket 7

    A long time ago, in a galaxy far away, there was a processor socket that fitted each and every consumer CPU.
    Sounds like a fairey tale? It is actually our own galaxy, at the end of last century and the socket is the so-called Socket 7.

    As Wikipedia states
    "Socket 7 is a physical and electrical specification for an x86-style CPU socket on a personal computer motherboard. It was released June 1995. The socket supersedes the earlier Socket 5, and accepts P5 Pentium microprocessors manufactured by Intel, as well as compatibles made by Cyrix/IBM, AMD, IDT and others. Socket 7 was the only socket that supported a wide range of CPUs from different manufacturers and a wide range of speeds."

    Intel decided to leave the socketed design for its Pentium-II and make that new socket -actually a slot, Slot 1- a proprietary one, so the other manufacturers were stuck at Socket 7 for the time being. Here enters the Super Socket 7, developed by AMD for their K6-2 and K6-III processors.
    As it featured a 75 up to 100 MHz frontside bus -depending on the chipset and the settings on your mobo- and support for AGP, the other CPU manufacturers were able to compete with the Slot-1 boards with their PIIs and Celerons.

    What could theoretically be fitted into a Super 7 board? (not all Socket 5 or Socket 7 designs will fit as the needed VCore value is sometimes unreachable)
