IBM PC - ECA001 - IBM PC700 Series Pentium processor replacement
Applicable to: World-Wide
PURPOSE:
THE PURPOSE OF THIS ECA IS TO PROVIDE A REPLACEMENT INTEL 90MHZ PENTIUM PROCESSOR FOR AN IBM PC 700 SERIES SYSTEM. THE REPLACEMENT IS TO RESOLVE THE "REDUCED PRECISION" FLOATING POINT CALCULATION PROBLEM.
INTEL HAS ACKNOWLEDGED A DEFECT IN ITS PENTIUM MICROPROCESSOR THAT CAN CAUSE INACCURATE RESULTS IN SOME MATHEMATICAL APPLICATIONS. IN SOME CASES THE PRECISION OF THE PENTIUM DIVIDE OPERATION MAY BE REDUCED.
