I noticed what neurokinetik said about the 7200 not existing and its 100% true.

The 7200 is people getting the 5200 and 7800 confused.Do an ebay search for atari 7200 and nothing will show up.
Also,its not in atari’s museum.

If you had an atari 7200,you should have sold it for millions because it doesnt exist.
