oracle_jedi Posted February 28, 2010 Share Posted February 28, 2010 I recently got one of the 32-in-1 OS upgrades for my 1200XL. I missing the resistor to solder onto the PIA. I have plenty, but I cant see the colours from the picture, does anyone know the resistance value to use? Thanks Quote Link to comment Share on other sites More sharing options...
Roydea6 Posted February 28, 2010 Share Posted February 28, 2010 This is the installation instructions: http://www.atarimax.com/warpos/documentation/install_guides/install1200xl.php I didn't see any resistor values. Quote Link to comment Share on other sites More sharing options...

Steve got back to me directly and said anything from 1K to 5K would be good. I used a 4.7K from my box and completed the upgrade about 30 mins ago, my 1200XL now has the Clearpic 2002, 256K RAM and the 32-in-1 OS upgrade, pretty sweet! That's enough soldering for one weekend, next time I might try to take it to 512K. Quote Link to comment Share on other sites More sharing options...
