Epoch Astro Thunder 7 (1983, VFD, 4 C Batteries, Model# ?)
This game has seen many different incarnations, here are the ones I know: Grandstand Firefox F-7, Epoch Astro Thunder 7, Epoch Galaga X6, and Radio Shack Astro Thunder. There may be more, I'll add them as I find them... :)
Do I have this? No.
