walter_J64bit Posted August 27, 2007 Author Share Posted August 27, 2007 Best has lost the XEGS upgrades I've called them not to long ago, is there a public domain upgrade? Quote Link to comment Share on other sites More sharing options...
Marius Posted August 27, 2007 Share Posted August 27, 2007 Best has lost the XEGS upgrades I've called them not to long ago, is there a public domain upgrade? I know there is a Atari genius here in the Netherlands, called Mathy van Nisselroy. He designed a 1MB upgrade for XEGS. The last news I heard about it was in 2002... and that was that it was 99% ok, but not 100% compatible or something like it. Perhaps it is 100% now? Ah here is the link: http://www.mathyvannisselroy.nl/ I'm not sure if it is on his site... but I think it is. Have fun! Marius Quote Link to comment Share on other sites More sharing options...

Marius I'm 90% done designing a 1M upgrade based off this design and Bob Wooley's , that will work in an XL, XE, or XEGS, based on a single GAL22V10. One chip, one simm, and you're done! I hope to release this by the weekend. I have it working in my 1200XL (the extra ram works, I'm trying to make it Antic compatible at the moment). There will likely be two different versions of the chip, depending on whether or not you have a FREDDIE chip... Quote Link to comment Share on other sites More sharing options...
