$74.95

The 1056 Board For the Atari 800 easily upgrades your Atari 800 to 48k of base memory plus 1008k of Axlon compatible banked memory for a total of 1056k of RAM. Unlike many other memory upgrades, this upgrade requires no soldering and/or tearing your computer apart. All that is required is for you to remove your current memory card(s), install the “Jumper Board” in memory module slot 1 and The 1056 Board in memory module slot 2. That’s it! The 3rd slot is available for other upgrades.
Extra Axlon compatible banked memory can be used for applications that support it, games that require the extra memory, a RAM disk (or disks), etc.
Instructions:Remove the top cover on your Atari 800 by opening the cartridge cover. Then either remove the 2 screws at the rear of the cartridge cover or turn the 2 latches so that your cover can be removed. Remove the cover. The front slot will have the Operating System. The 3 slots after the Operating System will have the memory modules. Remove the memory modules. In the slot closest to the Operating System, install the Jumper Board. The Jumper Board is labeled as to the direction that faces the keyboard. Ensure this board is inserted in the correct direction or else your Atari may be damaged. In the next slot, install The 1056 Board. This board is also labeled as to the direction that faces the keyboard. Ensure this board is inserted in the correct direction or else your 1056 Board will suffer damage. Re-install the top cover and enjoy.
Note: Pictures show the jumper board and 1056 board as well as the installation in an Atari 800. Atari 800 not included...of course.
