It is missing the left shift key cap. Here's a pic.
Also has the 48K RAM upgrade. Both upgrades were done before I purchased it. It has an Atari Service sticker on the bottom, so the upgrades may have been done by an Atari Service Center. I have not opened it.
I have the original keyboard, which I will include. I don't have the power supply, I think it was missing when I bought it.
I tested it using the power supply from my Atari 800. Everything seems to be working correctly. Played a few games, hit every key on the keyboard in memo pad. RF is pretty clean.
Shipping could be a little expensive depending on where you live.
If you want it, make me an offer.
Thanks,
Mitch
