I just bought this unit today. It is an original 4K version of the Color Computer 1. After fiddling with the inner RF box, I finally got a nice picture and the unit does seem pretty much untouched, even though the tamper sticker and screw under it was missing. I've tried a few cartridges I had laying around, but so far it doesn't want to play them. At most I get garbage on the screen or just a green screen, even after cleaning a few times. I'm hoping it's just a case the carts I am trying are too big for this unit's 4K of RAM. I have a slightly later unit with the 32K of RAM, but I always figured I would pick up an early 4K version if I found one in decent shape. And yes, it is only running Color Basic 1.0!
