Why build one when you can build 8, string them together in a primitive card cage and wire wrap the pieces together?
This is the accumulator and the ALU together for the first time. I need to build a test circuit and verify the connections before I video tape this part of the work. And notice I have space for a flags register as well as the B through E registers.
Because I can, and loose transistors aren’t all that expensive…
