"Alien Attack" by Tomy, vintage LSI VFD computer video game.

This is my classic Tomy "Alien Attack" VFD Vacuum Fluorescent Panel video game, with sound. It is essentially a stand-alone implementation of the classic videogame "Scramble", and arguably one of the best VFD games ever made. It works with 4 "C" size batteries (using rechargeables in this case) or with an external DC adaptor, and the VFD panel is a delight to use in the dark! Has two levels of difficulty, "AMA" and "PRO" (the second is faster and harder), and it plays very similar to the original "Scramble" game. Here, I'm playing through a complete level at "PRO" difficulty. I got this circa 1988 or 1989, and kept it in working order all those years.
