40 odd hours later, I finally have this game working.  Spent a lot of time with my head in the schematics fixing the connectors.  Had a number of wires that had either burnt or just fell off the connectors, but some of these had been put back onto the connector in the wrong location    Caused all types of problems and errors after I repaired the boards and first fired up the machine.

The squawk and talk was basically toast.  Replaced the caps with correct value ones, replaced 3/4 of the resistors as these were shot, replaced the 5V, had 2x blown diodes, put in 2 new trim pots and replaced the TDA2002 amp.  A number of IC's had already been replaced and were OK, I replaced all the eproms as I do for all my games.  The original eproms were in the bottom of the cabinet and when tested were shorts.  This board suffered from bad wiring and from having the caps replaced with the wrong value.

The aux lamp board was another that suffered from a connector problem with a wire in the wrong location.  Took out all of the transistors.

Now the bad stuff is out of the way I can start on the fun part of the cosmetics
