I'd be interested in hearing about what you are doing (explain exactly what
"games" you are playing).

I'd be willing to replace a board after 20 years if it meant I didn't have to
reset my Defender every time I wanted to play it, or reset the options on my
Joust everytime I fire it up.

Original with the possibility of major catastrophe down the road.
