I got tired of these old games just cluttering the shelves in my desk, so I decided to mount them on the wall:
I put some adhesive-backed Velcro on the back of the games and the loop side of the Velcro on the wall (with a couple of staples to help the adhesive). Now, when I want to play, I can just reach up and grab one for a dose of 1980 electronic blip goodness, and when I’m not playing, they display rather nicely.
