If there was a fan out problem, one could do a ripple ring for clearing
but that might require some timed circuits to keep from racing.
If you wanted to go really retro, implement the NANDS and diode-input
transistor sets. Assuming that the transistors have enough gain and
are beefy enough, you could extend it pretty far.
Or use diode array ICs and an octal buffer.
Anyone ever fool with ternary logic, building flip-flap-flops out of
3-input gates?
