Ultimate – 1MB RAM expansion for Atari XL/XE

Hardware, manuals, FAQ, and other info on manufacturers website – HERE

Ultimate is one of the best Atari XL/XE internal upgrades ever, invented by Sebastian Bartkowicz aka Candle’o’Sin. Installation of this upgrade takes approx. 5 minutes and even a rookie can handle it at home without finding a professional technician and extra costs!

It’s easy, it’s simple, it’s FUN! Also, in the present version, some fixes were applied in comparison to the initial releases. Now it’s 100% “safe and sound”. Of course, what would be a bundle of wires without software support?

Dear all, it is about time to visit AtariAge / AtariArea forums, isn’t it? 🙂

Before you start!

• If you are not confident with a soldering iron or you do not have proper tools, please LET a pro technician do it for you.
• Please remember – wrong tools usage or low skills may damage Atari and Ultimate. Any damage/harm to your hardware is NOT subject of warranty!
• Installation is easy, but inexperienced hands can do a lot of damage. Please, do not ask me questions WHAT HAVE I DONE WRONG WITH INSTALLATION – the answer will be always the same – I DO NOT KNOW

INSTALLATION STEP BY STEP:

• locate  MMU (20 pins) and OS ROM (28 pins) and their pins no1

The general rule of pin identification

• If Your chips are in sockets:
  • Remove  MMU (20 pins) and OS ROM (28 pins) chips from their sockets
  • Insert flat cable with “chip-adapter” side into MMU and OS ROM sockets ( RED STRIPE  cable indicates PIN 1 of the removed chip)
  • Make proper 4wire connection of ULTIMATE with CPU  – CLICK 
  • Connect flat cables with “IDC-side” to the Ultimate board ( RED STRIPE cable indicates PIN 1 ultimate connector)
  • Fix ULTIMATE PCB inside Atari
• If Your chips are not in sockets:
  • desolder MMU (20 pins) and OS ROM (28 pins) from atari PCB
  • Solder sockets into atari PCB (sockets are not supplied by me)
  • Insert flat cable with “chip-adapter” side into MMU and OS ROM sockets ( RED STRIPE  cable indicates PIN 1 of the removed chip)
  • Make a proper connection with supplied 4wire cable between ULTIMATE and  CPU  – CLICK 
  • Connect flat cables with “IDC-side” to the Ultimate board ( RED STRIPE cable indicates PIN 1 ultimate connector)
  • Fix ULTIMATE PCB inside Atari
