The Atari 400/800 3rd Party Upgrades & Products

The Antonia is an all in one 65816 and 4MB linear RAM upgrade module. While it would be difficult to install the Antonia into an Atari 400/800, it is possible with some modifications to the RF Chassis on each system to accommodate the height of the board as it would extend away from the CPU board on each system far more than space would allow. The CPU replacement is more geared towards installations into Atari XL/XE computer systems. The other very nice feature of the CPU upgrade is that it also has 4MB of linear accessible RAM on the board. The 65816 can address up to 16mb of memory in total.
