For your consideration is one used, tested and working game of Firefox.  Tested on an Atari CX2600, and 2600+, photo of game playing is on the 2600+.  This is an unfinished prototype, but desireble to collectors.
  
The backstory of Firefox (from AtariMania)…
 
"Found in the collection of a former Roklan programmer, it appears that someone at Roklan was working on a plane combat simulator, but this prototype is labeled Combat II and was in an official Atari lab loaner case. While various 3rd party games have been found in Atari lab loaner cases (usually for employees examining other companies games), this prototype was an unfinished WIP of a completely new and unknown game. The mystery was finally solved however when a very early demo version of the game labeled Firefox was found. Not only has the name Firefox appeared on several internal Atari lists, but according to the former Roklan programmer this game was being developed for Atari. It is unknown if development continued on past this Combat II labeled prototype, but it ultimately ended up not being released. Atari may have felt that a tactical fighter pilot game wasn't a viable option when fast action and arcade games were king. Another reason may have been that Atari didn't want to market the game as an official tie in with the 1982 Clint Eastwood movie for some reason."
