SoftwareFPU is a Macintosh utility which allows applications requiring a Floating Point Unit (FPU) to work on computers without one, such as the IIsi, IIvi, LC series, Classic II & Color Classic series, Performa series, Power Macintosh, and some models of PowerBook, PowerBook Duo, and Quadra series. Put the SoftwareFPU control panel in your Control Panels folder and restart and FPU applications that formerly crashed will begin working.
Mac OS Classic
||SoftwareFPU requires a 68020, 68030, 68LC040, or PowerPC processor. SoftwareFPU is fully System 7.5 compatible.
