EDIT: Found your earlier picture post here: http://atariage.com/...37#entry4256778
I forgot about those pictures, good stuff. I just compared the pictures against my 800XL install.
The wire connections all match up with mine.
The jumpers match up with mine.
It looks like there's some added solder on the +5 and G pads, or maybe a difference between the Bryan & MacRorie produced boards, but these two pads were bridged when I received them, did you cut the traces between them? I can't see that clearly.
I also installed mine into a socket piggybacked onto the 4050 chip. I think that was to keep the RF modulator functional.
Does the computer run fine with the UAV removed and the original 4050 replaced? (To confirm that some random solder blob didn't short something out...)
