A
processor made by
Intel in the early 90's. Was extremely
fast for its days. It was essentially a
486 chip that ran at
twice the speed of its external bus. You could therefore
plug an 80486DX2/66 into a motherboard that used to have an
80486DX/33 in it, and your
computer would feel twice as fast. There was also an
80486DX2/50, but it sucked compared to an
80486DX/50, which ran natively at 50Mhz.
Clock multiplying is now a way of life in the
computer industry.
