Nope, M68060 (not MC!) is Signetics (Philips) embedded microcontroller which has 68000 instruction set core, with two async ports, 2 DMA channels, two timers and (surprise!) segmented MMU! (I should verify these features, but my databook of that processor is at home..) Execution timings are not those of MC68000, thus a tuned optimizer could be considered -- it is slower on some common operations, than original 68k. It was developed for some Philips CD-player, and was very late.. >--- >Mitchell N.
