This is what Eric Smith tells me as well. As I told
him, it doesn't make much sense. The board has a 6502
as well as the 6507 with the data lines tied together.
I guess they could use opposite phases or something.
I was tracing down the sync signals for the video
and they seem to be coming from this part??
I do have a schematic someplace but I haven't located
it yet.
Now I have a mystery to solve?
Possibly it's a variation of the Lancaster TVT (Cheap Video) design?
What is it?
