I installed a working boardset to get my vintage Gorf upright up and running again. Player 2, however, flips the screen like the cocktail version. I've studied the documentation and do not see a dip switch that controls this. Is the screen flip controlled by a chip?
Welcome aboard, Whimsicalwill.
The last page of the manual
here indicates that there is a jumper (JU1) on the Game Board that switches beween cocktail (in) and upright. (out)
You can find the jumper schematic on pg 66 of the PDF, right side, half-way down the page, to the left and just below the dipswitches.
On the board, JU1 is located on the right side center, just below the dipswitches in
this photo.
