Finally got around to working on some of my other Pole Position boards... after looking at a couple that stood out; I noticed they were PP2 boards. I paired the boards with working PP1 boards, the CPU board originally had some RAM errors, fixed that and it's working, as best as can be expected, when paired up with a PP1 Video board. The PP2 Video board acts the same way with a PP1 CPU board. I believe both problems (the sync and the blocks for graphics) are related to a single fault.
