I have an original Super Zaxxon PCB that I pulled out of a cocktail cabinet. It was set to some sort of free play so your game never ended but everything else seemed to work fine. $50 plus actual shipping from Canada (probably $25) and it is all yours.
I got a complete working zax and another complete zax minus monitor and 1 extra complete CP, Id like to sell all of it as a package deal. PM offers Might have a extra board too, have to look. I can email pics to anyone interested.
