Tiger Miner 2049er (1983, LCD, Watch batteries, Model# ??)
This is a neat little game... For those that don't know (or don't remember) Miner 2049er was a computer game developed by Big Five Software and originally released on the Atari 400/800 computers. It was eventually ported to the Atari 2600, Atari 5200, Commodore 64 (the version I remember playing), IBM PC and obviously licensed to Tiger to create this handheld version of it. Check out the website for Big Five Software for a little history about the game (the company is no longer in operation, but the founder put up a little website with some company history).
Games in the 'Double Wide Screen' series (6 found so far): A-Team, Lucky Luke, Mickey Mouse, Miner 2049er, Pac Man and Smurf/Schlumpf/Schtroumpf.
Do I have this? Yes, boxed.
