Ok, Thanks for the posts! The one big unknown was the Atari 2600 Wireless Remote Base ! It looks like it was de-cased and mounted inside the 800.
Yeah, 800 frank-n-stein came to me like this in busted up condition, i will try to dump the roms and see if i can find out what was on them, there was some dev/programming carts in the box, along with a rom programmer. ( for the Atari 800XL )
