Congrats on your recent ebay purchase!
Ahh - the only way I could play light cycles back in the day!
(at least the only way at home)
I got my Tomy TRON game in 1982. I think I got it the same summer I saw TRON in the theater - I was 11 then. It was TOTALLY AMAZING to me!
I spent MANY an hour on that digital bundle-of-joy wrapped up in such a small package. Light cycles was always my favorite game on it, but going up against Sark in the disc game seemed to be the longest time spent per round. I don't remember my high score, but I used to be able to get several bars across (1 bar represents 2000 points) before Sark could do me in. The really cool thing about the light cycle game is that it scrolls off the screen and the movement is not limited to the size of the screen as the playing area.
I loved that it played THREE games! Light cycles, deadly discs, and a shot against the MCP himself! I still have my game, and still play it from time to time. I'm not nearly as good as I used to be on it, but I can still rack up a good healthy score
What a GREAT game!
