Tiger Space Invaders Tabletop (1981, LCD, 4 C Batteries, Model# 7-??)
Just recently re-discovered on Ebay (March, 2006), this is, with out a doubt, the rarest of the Tiger tabletop games (unless someone can prove Star Castle exists). This is the only one that I've ever seen (and it doesn't even work). Up until this time (seeing it on Ebay), I didn't think it had ever been produced...
Games in the Tabletop series (5 found so far, and 1 Unreleased): Jawbreaker, King Kong, Monster Maze, Smurfs, Space Invaders and Star Castle (believed to be Unreleased).
Do I have this? No.
