CPUWIZ Posted June 15, 2015 Share Posted June 15, 2015 Hey guys, I finally got around to picking up one of the LH mods and I am looking at the install pictures in disgust. Can anyone tell me if the removed resistor spot and the adjacent resistor are bridged (TIA9)? http://electronicsentimentalities.com/7800InstallationInstructions.html 1 Quote Link to comment Share on other sites More sharing options...
jaybird3rd Posted June 15, 2015 Share Posted June 15, 2015 That picture is very ambiguous. I did NOT bridge the TIA9 solder point with the neighboring resistor when I installed mine, and it seemed to work as intended. Quote Link to comment Share on other sites More sharing options...
CPUWIZ Posted June 15, 2015 Author Share Posted June 15, 2015 Ok, thanks, indeed terrible pictures, I may post some better ones, including an alternate version of the BIOS mod, that works along side the video-mod (Dan's method wouldn't work with the video mod), if I ever get around to actually installing it.

alex_79 Posted June 15, 2015 Share Posted June 15, 2015 There's a an installation guide with pictures and a pdf with the schematic on Longhorn's website. That's for v2.1, don't know if it's the same revision board that ElectronicSentimentalities sells.http://longhornengineer.com/deprecated-static-pages/diy/atarivideomods/7800-ntsc/ http://longhornengineer.com/images/atarivideomods/design/Atari%207800%20Video%20Mod%20V2_1.pdf Quote Link to comment Share on other sites More sharing options...
