Very pretty! Somebody else made up a digital clock from some HP AC4 (or
similar) decade counter modules, but I can't find the web page now.
I have enough extra AC4 modules to do the same but I don't want to think about
the cost of running and maintaining such a thing 24/7, so I'm sticking with
just powering up my tube counters every now and then.
