Vtech Sonic Invader (1981, VFD, 4 AA Batteries, Model# ??)
Plays like a cross between Radio Shack/Tandy Fire Away series and Space Invaders. Identical to Vtech's Invaders, just different name and case design. (Also released by Grandstand as Cosmic Invader and Prinztronic as Galactic Invaders.)
Do I have this? Yes, loose (this is mine pictured).
