I am sorely tempted to shelve the ID/CU, and /temporarily/ replace it with an ESP32 surrounded by resistor packs, 74F138s, and 74F157s. I know if I do that, though, I'll probably never finish the real thing. Also tempted to use at least a PIC16F84 in what I'm hoping will eventually become at least a rudamentary MMU, which I see as the primary barrier to running something approaching an OS on this thing, apart from, you know, actually getting it to work at a satisfactory clock rate.
