  HP pocket
clacs, Microwave ovens, quite a few games, small army

I've got a vintage HP clac, but wouldn't that be using a custom circuit

yes and yes.  It was a custom circuit but the circuit was a 4bit
microprocessor that HP did for their own use.  Bell labs also had
a really interesting 4bitter they used in ESS (early).
