Thanks for the responses everybody, great stuff.
whicker, just to clarify: are you saying that (as far as snes goes) the HC and HCT will both work, its just that HCT is always seen for some reason ie cost/availability? Your example of your hobby experiment went right over my head, was it just to illustrate that there are non-snes cases when the two wouldn't be comparable? thanks again.
yes, there's plenty of noise margin and settling time that any 5 volt 74xxx series will work. and yeah, my contrived example is when things start to work unreliably.
just watch out for cold solder joints, meter long wire lengths acting like antennas, and remembering to actually power the logic chips (VCC, GND).
