I have a semi-functional Gorgar to go along with my semi-functional pinball repair know-how.
I'll start with what works:
Scoring, GI, flippers, targets
What does not:
Jets, slingshots, snake pit magnet and the thingie that kicks the ball over to the plunger after you drain
I've reseated all of the chips and that awful 40-pin interconnect (because that's what everyone says to do whenever there's a problem with this system). All of the fuses look ok (though I may swap them out today for posterity).
Any suggestions as to what I should explore repairing next are greatly appreciated!
