ABSTRACT:
A switching circuit controls the routing of various signals of the computer system to and from the various pins of a microprocessor socket. A microprocessor rests in the socket and can be removed and replaced by another microprocessor. Variations in the pin arrangements of the two processors can be compensated for by appropriately setting the switches on the processor card. The use of 486SX, 487SX and 486DX microprocessors is illustrated in a single socket.
