Takara Dougram (1982, LCD, 2 x LR44s, Model# ??)
Based on Fang of the Sun Dougram, a Japanese Anime cartoon similar in theme to the Gundam series... Joytronics Card & Action series, comes with a cable so you can attach another game for play. You can connect up to 4 games. There is also a large connector at the top of the game that appears to be for some kind of add-on, but I'm not sure what it's for. Takara made five games in this series: Banana Boat, Dougram, The Gang, Hamburger, and Kangoku Lock.
Do I have this? No.
