Here is my Christmas gift from my folks in '81 (or '82); Coleco's Donkey Kong tabletop game. I am the original owner! Its works awesome, even after it sat all those years. The controls responded fine, but I cleaned it up and it responds even a little bit better now. The blue plastic is still bright everywhere and so are the graphics on the sides and top. No fading from light or time. The plastic decal affixed under the joystick and Jump button is shiny and stuck down. I cleaned the screw for the joystick as well. This thing looks much better than the pictures indicate, I just try to provide the most info possible.
As for blemishes, most of them are minor and really don't take much away from showcasing it and definitely doesn't affect game play. They are: minor surface scratches, mostly on the sides (not actually damaging the decal but impressions, mostly. Light ones on the view screen (the camera makes them look way worse (imho), light scratches on the back and bottom from use, plus the curled decal on the left side (right top corner). The decal on the top has curled VERY slightly on the bottom right corner The other decals are in great shape.There's also some very light yellowing where the back clips around and on the bottom edge of the blue on the back. Bottom foam (?) pads are gone but the goo that held them on is still there.
I'm also including the Perma Power adapter that I got along with it--- replaced the "C" batteries back in the day and is what is powering it now! It's got some weird jacks along the cord, which is pretty long. The battery case is free from rust and/or corrosion.
Use your judgement from the pic;s they tell the story and I've tried to document everything as accurately as I can! Please feel free to ask any questions.
Thanks for looking!
