I have a game called Astro-Grover that says it is for Atari 600XL/800/800XL/1200XL that I don't see in the rarity guide. I know it's not in there because it's not a XE compatible game. Anyway, I am just wondering if anyone has an opinion of rarity or value. The items are in fair condition, the keyboard overlay shows wear as does the case but everything is intact. I don't know if it's complete, it comes with everything in the picture. I am probably going to put it up on ebay because I don't really want it. Thanks for any input.
