Atari 400 Factory 48K Memory Expansion Kit.
This Atari 400 memory upgrade product was released late in the Atari 400 Computer product run and many Atari 400 Owners never saw it. We think Atari Engineering did not want to produce this product, but many other companies had already developed 400 Memory Upgrade boards for the Atari 400 Computer. Atari Sales Department finally got their way and released this Atari Engineering designed 400 Ram Upgrade board. Other manufactures versions of this 400 Ram upgrade boards, required you to do circuit board trace cuts with 400 motherboard trace jumps or add an extra daughter board with components into a socketed I.C. chip location or swap out I.C.'s on the Atari 400 Motherboard to get their 48K Ram cards to properly work on the Atari 400. Although one of the last 400 Memory upgrades to be produced, Best Electronics rates this Atari made 48K Ram upgrade board as one of the Best ones ever made!
To install this Atari Factory made 48K Expansion board, requires you to solder / install 4 jumper wires (above 4 Red wires) to the bottom of the 400 Atari Motherboard (no circuit board trace cuts) and with a pair of diagonal cutters, cut / clip two black plastic old 16K Ram Card support brackets inside the Atari 400 Die Casting, to make more room inside the Die casting for the larger 48K Atari Ram Card. That's it! If you used the Atari 400 / 800 Factory Diagnostic Cartridge on a 400 computer upgraded with the Atari Factory memory card, it would think you were testing an Atari 800 with 48K of memory. All Atari and other 8 bit companies 800 made Software that required 48K of memory we have ever used on a 400 with this Atari Factory Memory Expansion board installed, ran 100% of the time. Requires a Phillips Screwdriver, Solder Iron, Solder, Diagonal cutters and an Atari Basic Cartridge to verify total memory after the upgrade. The 10 page Atari Installation Pamphlet is well documented with many pictures and step by step Installation Instructions. 4 precut red jumper wires and fully populated 400 48K Ram Card.
