Ladies, gentlemen, people who don't give a fuck, and creatures of the night, it works! I now have a working ADD, ADC, AND, OR and XOR instruction, against the [PC] (memory pointer for the current address on the stack), U and V registers. The modified boards I got back did the trick nicely and as a bonus I didn't even have to put the ADC carry-handling PCB on a different acrylic sheet! I can't double-check the U and V versions because I don't have the instruction decoder built to load values into those registers yet, but they're responding to load requests and putting "0" on the bus. Now it's time for me to tidy up the board and then permanently install it in the #MiniDragon stack!
