This page is graphics intensive. It may take a few moments to load. You know, I have never figured out why Atari had so many unreleased products. It boggles the mind to think about all of the great ideas that never made it out the door. Some say that Atari was ahead of it's time with some of these devices.
Many people feel that management was incompetent.
Whatever the reason, many products never made it off the drawing board. This modem plugs directly into the Atari Jaguar DSP port. This unit used the Atari Jaguar power supply, then had a cable that came out of it that plugged into the Jaguar to feed it power. If a call came in while the modem is in use, the game would pause, and you could take the other call. The only game with Jag Modem code written into it for use with the modem is Ultra Vortex.
