Quoted from thepinballworks:I am surprised they are not on Stern's site. A paper manual did come with the game.
You do realize that there is a complete wiring diagram in the rom if you just hit the info/draw button in Diagnostics while on the device/wire/light/switch in question.
Pick draw and it will scroll through the transistor, jumpers, wire colors, etc.
Not only did stern do this, All WPC Williams/Bally had the feature too...
All the manuals were on the Stern site in PDF until the last redesign of their site, then someone removed them (probably so they could make money from reprints).
