What is the relative speed difference between a 68000 and a 6502 (or 65816) which are both running at the same clock rate? I've heard various (and often contradictary) answers to the question, but have never heard the rational behind the numbers. Thanks for any help, Paul R.

Any such number is meaningless, unless it was obtained by timing the actual application(s) that you care about. The 65* series pipelines instructions, whereas the 68K family has generally more powerful instructions. On an Apple, peripheral (slot) I/O cannot proceed except at a 1MHz clock rate, since some controllers depend on this for timing.
