More wiring done here! The whole button assembly works as grid with addresses- by choosing a vertical input and a horizontal input, one Button may be individually adressed. You can start to see the grid system here- the copper rails are the vertical inputs, and the blue wires are the horizontal inputs. And the messy junk on the right edge is the newly installed transistors for the horizontal inputs...
If you're interested, you can see a full schematic here.
More wiring finished- here i've connected the transistors and finished wiring a couple of the switches. I'm not sure how the rest of the machine will play out yet, but there definitely isn't any more room on this board for the logic board, so i'm routing wires to the transistors. They also serve for testing purposes!
