One of the boards I designed simply does not work. Worse, it’s not a simple error: I can’t simply cut one or two lines on the board and run jumpers. Turns out a bunch of resistors were incorrectly wired to power–and cutting them would require so much work it’s easier to basically start over again.
And it was such a rookie mistake, too.
That means my hope for having the accumulator and flags registers connected to the ALU will have to wait a few weeks. Meanwhile I suppose I can start building the B through E registers…
