7800 Computer Add-on

The docs keep on coming....


Ok, up next in the Atari 7800 section is the programming guide to the Atari 7800 Computer Add-on. Its a good 21 page document which discusses how the 7800 and the keyboard negotiate communications and how the system address' SIO devices and so forth, makes for some interesting reading.


Plus the 7800 section of the Atari History Site has a nice new look, the top header is from a prototype 7800 Prosystem console and you'll note it does not say ProSystem on it. A photo of the original 1984 box with the lettering across the bottom left corner detailing how the system is expandable into a computer and so forth (a label was placed over all original 84' 7800 boxes when they were finally sold in 1986). Also one of the original 1984 cartridges as well.


Hope everyone is enjoying these new bits of information and images on a side of the 7800 many never knew about in detail. Enjoy!
