Thanks for the update. I have 3 units (2 functional) and am in for at least 3 screens. I agree with tg517 - there are many units that only need a screen to restore them to a playable state.
I had one when I was a kid - didn’t keep it . Having grown up during that time, it is my opinion that the storage/transport requirements kept this awesome game from staying out-front in the portable game marketplace. Unlike today, no one was offering accessories like padded carry cases targeted at portable video games. As I recall, the MV won’t fit in the typical camera case of the era.
