Description

Oh The ultimate memory upgrade for Atari XE/XL 8-bit computers.

Ultimate is one of the best ATARI 8bit internal upgrades ever, invented by my great friend, Sebastian Bartkowicz aka Candle’o”Sin –  http://spiflash.org/ . Installation of this upgrade takes me 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 release. Now it’s 100% “safe and sound”. Of course, what would be a bundle of wires without software support?

Features

  • As solderless as possible (only RW, PHI2, HALT and RESET lines need soldering when MMU and OS ROM are socketed)
  • fully flashable SpartaDOS-X with up to 320kbytes for its purposes
  • Real-Time Clock module for SDX with battery backup and NVRAM
  • fully flashable 4 OS ROM slots
  • hardware WRITE PROTECT for the whole Flash array
  • configurable memory expansion with 4 modes of operation (disabled, 320k RAMBO, 578k COMPY SHOP, 1088k RAMBO)
  • customizable BASIC and MISSLE COMMAND slots (also flashable)
  • compatible with all XL/XE machines (600XL needs 64kB of RAM first)
