Thanks for the information. It looks more and more like I'm going to need the SIO2PC adapter.

Does anyone know if their is a utility that allows the playing of cartridges that were for the 400/800 only on an xl/xe machine. I just picked up the game Fort Apocalypse on cartridge, on ebay for $8.00 but it wont play on my 800xl and I dont want to have to set up the 800 to play 1 game. Any sugges...

I actually have the MegaCD interface that uses a standard Cd player. But like you I am looking for addition information.

Does anyone have any information with regards to the MegaCD interface and Cd that workks with the Atari? I have one but I don't have any information about it. Was this a commercial product? Was this a user made item? Does more than 1 CD exisit for this? Any information would be appricated.
