People seem to like to say "The effective 68000 clock rate is only x MHz"
where the x is replaced by some number from 3 to 7 depending on the
person's opinion of the mac.

According to Byte mag, it's around 6 MHz, more if you are doing
graphics or some other type of program which spends lots of time in
rom.

Incidentally, one may not like it that the clock speed is effectively
lowered, but bear in mind that the I*M PC/AT has a clock speed of 6 MHz
with one wait state.  (:-)
