calfranklin Posted January 17, 2012 Share Posted January 17, 2012 Is the ram memory in the XEGS upgradable to 128K? Quote Link to comment Share on other sites More sharing options...
jaybird3rd Posted January 17, 2012 Share Posted January 17, 2012 Yes! I posted a scan of the parts list and installation instructions for the Innovative Concepts upgrade a few years ago; see a subsequent post for an easier-to-read ASCII version. With the exception of Atari's CO25953 chip, all the parts referenced in the upgrade are standard components. The RAM is a pair of 41464 chips, stacked on top of the existing RAM.

puppetmark Posted January 17, 2012 Share Posted January 17, 2012 <p>I did the upgrade using the instructions posted here and it works great. I got the CO25953 from Best Electronics. Quote Link to comment Share on other sites More sharing options...
sloopy Posted January 17, 2012 Share Posted January 17, 2012 May be easier, and more functional to use Candles Ultimate 1Meg board... this would give more ram and SDX built in... sloopy. Quote Link to comment Share on other sites More sharing options...
