....Interestingly enough, I had the same problem (either edge triggered)
using a totally unrelated IC, the TRW TDC1007J (flash A/D). But its
either-edge-triggeredness really wasn't here, it was how I was generating
the system clock (delay line XOR-multiplier).  The state this circuit
comes up in can really mess up your mind; if you've got state of the
art VLSI in one place and even faster STTL in the other.

....Could it be that the CoCo generates system clock by multiplying up
the colour burst (63/88 * 5 000 000; ~~ 3.58 mc) using same said circuit?
Is it getting into a funky state on power up due to the indeterminacy of
how the {insert-your-rate-muliplier-here} comes up ?? Eagerly awaiting
answers..
