The Intel 486 came in two versions: the 486, with math coprocessor, and the 486SX, "without" coprocessor. The chip itself was the same (why have two fabrication facilities?) but one version had an extra pin to enable (or disable, I can't remember which) the coprocessor. | REALLY? The story I heard was that the difference between the 486DX and the 486SX was that all 486s had math co-processors but the ones labeled and sold as SXs the math co-processors had failed in the QC process .... so instead of throwing them away they just renamed them sold them for a slightly reduced price and sold the ones that worked properly for more $ as DXs.
