The game works - the video was too large to upload here but is on YouTube - see link below. It is pretty amazing to experience something so primitive that was cutting edge at the time.

Please see pictures for condition. I had some difficulty switching into the Squash game, I had to nudge the selector to the left to get it into the correct position, otherwise the screen would display the Squash and Practice games at the same time. The original manual and any other paperwork that came in the box is no longer present. 

I will ship the JC Penney box inside another box. 

Let me know if you have questions. 

Thanks, 

Alex
