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.

FJC has written an extensive user manual here: CLICK ME

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<
