Ok, stupid question.
I know that the Q clock and the E clock are 180 degrees out of phase,
and that the CPU uses this relationship to separately clock different
internal states. But when reading instruction set timings, a cycle is
one complete cycle of the E clock, without respect to what Q is doing
(though their period is the same), is that correct? So at 1.78 MHz, 1
cycle of the E clock is a little more than .56 microseconds, if I
understand this correctly.
Just looking at Sockmaster's Hicolor code and thinking about how much
processing could be done during the scan lines, vertical blanking, etc.
