While pulling some Sprint 2 boards I came across a little collection of Atari Dragrace PCBs. Of course, untested. I'm thinking $80 shipped which includes tracking number. PM with questions.
I actually tried to find your ad last night via the search feature with no luck. I assumed you removed the post or something (can you even do that?) but NOW I see why I couldn't find it. I searched for Drag Race and Drag Racing...not Dragrace. Argh! Was also on an iphone further impeding things.
