Luigi301 #1 Posted October 4, 2017 I've got a U1MB upgrade that I can't install in my XEGS because none of the chips inside are socketed and I don't have the ability to desolder DIP ICs. I'm looking for an 800XL with the socketed MMU and OS ROMs that I can install it into. Quote Share this post Link to post Share on other sites
