Message text written by INTERNET:classiccmp@u.washington.edu Atari. < "Machines" really isn't the operative word; for instance, the list does not include the Atari Pong, 5200 and 7800 game consoles. I assume what you are trying to put together is a list of Atari "computers". That in turn takes some philosophical interpretation as to what constitutes a "computer". The 2600 game console is on the list; I assume it's there because Atari made a BASIC cartridge and a so-called "keyboard" controller for the unit, so it was technically possible to do some quasi-BASIC programming on it, not unlike a real computer. Of course, it only had something like 50 bytes of RAM available (not 50K bytes; just 50 bytes). The number of keys on the cheesy "keyboard" controllers were so few that each key had to do triple duty depending on what "color mode" it was in at the time. (If that didn't turn people off on BASIC programming, I don't know what would.) t had no way to attach a printer, and it could not save to or load from tape (or any other storage medium), so any programs developed could not be preserved. So, is that a "computer" or not? Then, Atari produced at least some "real" add-on keyboard units for the 2600. I believe they were originally called "The Graduate", but made it to market in 1982 as "My First Computer". They had 8K, expandable to 32K, and apparently saved/loaded from standard cassette units. So does the 2600 become a "real" computer at that point, and/or should "My First Computer" be listed instead or separately? (For that matter, the XE Game System, which is on the list, only becomes a "computer" when the separately-marketed keyboard is added to it; otherwise, it is strictly a cartridge game machine too.)
