I LOVED some of those early coin games. There was a deli on the corner where I lived where I'd spend tons of quarters on games like that...
"CHICKEN! Fight like baby robot!" - The graphics were not incredible, the game play was not so great but it was so much fun. It was SO worth a quarter...
Pre-amiga... Seeing an amiga 1000 run crazy graphics and sound made me realize I could bring that experience (or even better) home in a big way.
Seems like an obvious connection to me.
