Greetings,
I have an Atari 400 for sale that has been upgraded in the following ways. 1056k memory expansion designed by reifsnyderb, S-Video also from reifsnyderb ( you'll need a monitor with S-Video to hook it up to) and an IAB (Internal Audio Board) sound board specifically designed for the Atari 400 by the Brewing Academy. The only down side is that the SIO Port does not work. Crossbow was the one who upgraded it for me and he tried everything he could think of to get it working but no go. So if you know how to work on the 400, or know soneone who can maybe you can get the SIO Port working. Of course have two controllers with it and the power supply. Pictures after the listing of cartridges.
Also have 24 cartridges that I'm selling with it. 23 games and the Basic cartridge. games are as follows:
Frogger, Star Wars, Galaxian, Jumbo Jet Pilot, Submarine Commander, Qix, Asteroids, Defender, Star Raiders, Super Breakout, River Rescue, Space Invaders, Centipede, Missile Command, Jungle Hunt, Space Shuttle A Journey into Space, Demon Attack, Pac-Man, Ms. Pac-Man, Dig Dug, Donkey Kong, Buck Rogers Planet of Zoom, Computer Chess.
Asking price is $150 plus shipping.
