Commodore SX-64 portable computer keyboard. This was properly stored in a dry indoor location for many years and the keys etc. appear to be correct and complete. There is a small rubber bumper that is missing on one side of it, looks simple enough to replace (?) It would clean better than what you see in the photos. If you have a broken or missing keyboard, this could replace it.
The rest of the computer is available in separate listings. There are some additional photos at the end for reference only.
I am not the original owner of and have no way to try it out so being sold as found.
Probably best for someone who is familiar with electronics.
Good luck!
