S Posted December 16, 2004 Share Posted December 16, 2004 Hi All, I am trying to mod my 7800 for A/V outputs, and I have referenced both Saundby's page at http://www.geocities.com/atari7800mod/7800...nstruction.html and also Lee Krueger's page at http://home.earthlink.net/~resqsoft/7800_mod.htm, but it looks like they both refer to earlier board revisions. My board is one of the later revisions (PAL system) and has a part number of C300633-001 and the rows of resistors next to the modulator that is mentioned in the two sites above is not present on this board. I have included two pictures (one of the full board and the other of the top left, around the modulator). Please excuse my lack of electronics genious, but I will be grateful if someone could assist me in determining the points where I can connect Saundby's circuit to on this board revsision. Thanks for your help. Quote Link to comment Share on other sites More sharing options...
+Mitch Posted December 16, 2004 Share Posted December 16, 2004 Yes, the PAL board is different from the NTSC one. If you do a search on the forums you should find a thread with more info on where to connect the wires for the PAL board. Mitch PS. I also resized your pics for easier viewing.
