Tandy Cosmic 3000 Fire Away electronic game VDF retro vintage same as CGL Invaders 10000

The great Tandy Cosmic 3000 Fire Away in fully working condition. I collect VDF games and after a recent trip to Japan (check out Super Potato if you go to Tokyo) and buying more I need to make some room so selling my unboxed versions of games. Great condition, no rust on battery terminals and the speaker works perfectly. I don't know the polarity when plugged in to mains so haven't checked the mains input jack. Will be packaged as I'd like to receive a game from the 80's!! This is the same model and game as the CGL Invaders 10000 game but with a different badge At time of listing I'm also selling a CGL Puck Monster VFD game (Pac Man copy)
