The Dynacom doesn't really count its just 2 keypad controllers in a single plastic case, the Atari cx-50 keypad controllers were the original, so thats not a computer. I've never seen the Dactar-Comp, but Dactar in general did nothing more then make knock off clones, so I would think they most likely were probably going to remarket someone elses product under their look/name. Others were the Atari Graduate: http://www.atarimuseum.com/videogames/consoles/2600/a3000.html The Entex Piggyback and the Unitronics Expander: http://gamesmuseum.pixesthesia.com/history/gen2/2600/2600comp.html Curt Alexandre Souza - Listas wrote:
