mimo Posted May 13, 2013 Share Posted May 13, 2013 Anyone got the original longhorn engineer installation instructions? I had this mod fitted to a 7800 then put it in a 5200. Want to put it back in a 7800 now Quote Link to comment Share on other sites More sharing options...
Vitor Leonel Posted July 9, 2019 Share Posted July 9, 2019 I also needed longhorn´s 7800 video mod instructions. Bought this mod back in 2010 and now his web site is offline. Does anyone still have the wiring diagram? Thanks. Quote Link to comment Share on other sites More sharing options...
RevEng Posted July 9, 2019 Share Posted July 9, 2019 The site is online for me. Let me know if you still can't hit that link. Quote Link to comment Share on other sites More sharing options...

+-^CrossBow^- Posted July 9, 2019 Share Posted July 9, 2019 Keep in mind the location for the yellow audio is wrong on that link and you need to attach the wire to the top of the resistors not the bottom. if you follow that exactly you will end up with low Pokey/external audio volume compared to the TIA. 1 Quote Link to comment Share on other sites More sharing options...
