I think the Mac is set up in a way similar to the Atari 800. On the Atari,
the 6502 is run at 1.8 MHz, but the display hardware steals enough cycles to
make the effective rate ~ 1 MHz when running in text mode or 320 by 192 mode.

I believe the Lisa 1 ran at a clock speed of 5 MHz, so that it could use the
same trick as the Apple //.
