While my Challenger is working OK I realized I don't have everything I need in case it poops out. Thanks a bunch if you can help me complete my records.
I have found a manual for a different revision -- the cover page looks like the image below. But my game does have the Program and Reset buttons so I'd love to get the right manual for it. Schematic too... Anything! I did just find this great post by @coinopshop with pinouts and programming info but if you have a line on the official manual, please LMK!
