If you’ve built a PC gaming rig before, you know the kind of horsepower needed to run today’s games at their maximum settings. The most powerful computers are pushing resolutions past 4K and frame rates upwards of 140 FPS.
While today’s modern computers have 16+ gigabytes of RAM, the Atari 400 has a modest 16K. The Atari 800 offered an upgrade to 48K. With this handy upgrade card, you can make that same upgrade work for your original Atari 400 computer.
To get the full 48K, you need to install 4 wire links on the back of the 400 main board. You can still use the card without this, but you’ll only get 32K of RAM. With the standard version of this computer, the games you can run are limited, but the extra boost in memory will offer a wider selection of classic titles.
The upgrade is completely reversible as well. The kit comes with the PCB and all parts, including a pre-programmed GAL or a completed board ready to install. For those interested in further mods, this seller also offers a composite video output kit for the Atari series of systems.
