Does anyone out there have a *real* Joust manual with the schematics? I need to verify a value and it seems all the scans on the 'net are the same.
On the main CPU page, in the lower right corner, I would like to know the four "VA" address lines going to 5A (7404 inverter) and 4C (7421 AND). It appears to be VA0, VA1, VA2, and VA3, but the VA3 might be VA5, or VA8, or something else. Any confirmation would be greatly appreciated!

I found the answer. The schematic is wrong. The inputs are actually VA3, VA4, VA5 going to the AND gate, and VA2 going to the inverter.
