Hey, everybody!

After much meditating, how the Atari 2600 "thinks" is
becoming clearer.  But I would like to ask a couple
more questions first.

1)  How did they come up with the color clocks/machine
cycles?  I don't mean how did they measure them, but
rather, what reasoning did they use to come up with
having the TIA count color clocks and that three of
them equaled one machine cycle?  Was that simply the
limits of what was available at the time

It was three clocks from a 3.58 Mhz that equated to a single machine cycle. The TIA used the signal at 3.58 Mhz because that was the color burst frequency.
