(I think that poster was correct about the 8 MHz clock though; I don't think that Apple is using the 10 MHz or 12 MHz 68000 chips.) From a hardware standpoint, the effective clock rate *IS* 4 MHz. That says virtually nothing about the performance of the MAC relative to any other computer. The intent of my article was to correct the poster's erroneous assumption about the writers of the compiler he was using. -- ++--------------------------------------------------------------------------++ || Gregory M.
