I have a question for the really knowledgeable persons here. I have 2 5200's and a stack of 7 5200 mobo's (2 are two port and the other 5 are 4 port) fully populated that I picked up as spares. I also have a VCS adaptor that doesn't work in my complete 5200's (4 porters of course with no * in their serial) so I was deciding whether to mod them to work with the VCS adaptor or just run a 2port board in my 4 port case, when I noticed something really strange about one of my spare 4 port boards. First off it has a different # than the other 4 port boards, it has a different chip count than a 2 port and 4 port (two more than a 2 port and 1 less than a 4 port), has all the screen printing and traces of a 4 port in most areas while having 2 port design in it also, especially pin 24 of cart port is separate in the etched board not modified, just like the 2 porters. The #'s on the board are, Component side: CX5200P CA0 REV
Solder side: Atari 1982 C019673 REV 3
That's all there is on it, and I have not been able to find these #'s anywhere on the web, I'm wondering if this was an early prototype before the 2 port release, because this has features made into it like a two port but still has all four ports. This board has no jumpers or other visual signs of modding of any kind, looks factory new. Any ideas? Anyone
