Logic design with realys have different implmentations as a bistable with
gates can be one relay. Stepping relays are inherent counters and can be
made to count to any amount.

I've used realy logic for machine control, operating speed 2 to 5 sec per
interation so fast was not a required thing. Doing sequential work using
relays and switches is really fun. Of course all that drove air valves
so there was air logic too. ;) Oh, and you can do logic with air valves,
air one shots, even flipflops.
