Ultimate 1MB Upgrade

      Ultimate is one of the best ATARI 8bit internal upgrades ever, invented by Sebastian Bartkowicz aka Candle`o`Sin.  Installation of this upgrade can take 5 minutes or it can take two hours.  Depends one f your machine is socketed or not.

     It's easy, it's simple, it's FUN! Now it's 100% "safe and sound." Of course, what would be a bundle of wires without software support ?

  Here at The Brewing Academy, we ONLY sell the Ultimate 1MB upgrade with Jon "FlashJazzCat" Halliday's firmware already installed.  He is compensated with EVERY unit by TBA directly.

I use these primarily for 1088XEL & 1088XLD builds, but you can put them in your XL/XE machine as well.  If you are looking for something like this for your 800, look >HERE<
