Sounds like it's really well covered ;-)

FWIW, the three boards I found at a fast look through the pile are also all Rev A.

  I have 2 326298 rev a boards I don't mind hacking apart and taking pictures of in the name of science. Let me know if you guys need anything.

    that pic helped me solve the dammn RP4 mystery..

    on the schematic R51 should have been labeled RP4... 

    it connects to pin 4 of the expansion port which on the pic goes to Rp4

      I added head-on pics of the 326298 Rev A and C boards. Sadly, the back has a metal shield soldered onto both boards that will be difficult to remove and I'd like to keep these as working boards so front pics only.

            The VIC chip on those boards is a R5, which gives the clearest picture. "

        Not quite... You can get a clear picture from a 6569R1, 6569R3 or 6569R4 (that one is rather rare) as well. The problem on the older boards is mostly the modulator. Replace it with a simple video amp and you will have a very good picture. Ok, you lose the RF output, but who is using that anymore?

            It also has the 8 pin video port, not 5 pin like the earlier ones.

          Which is also not fully correct. Should read "like some of the earlier ones". Not all earlier boards had 5-pin A/V socket.

        Even the old KU board already has the 8pin Video out.
