High Speed page!

Purchased locally in March 2004.  It was partially working.  None of the special solenoids (pop bumpers and slingshots) were working.  The GROUND trace on the back of the MPU had burnt and was missing about 1 inch.  I bridged the gap, changed all 12 transistors (pre-drivers and drivers) and that got them working.  Next problem was that the special solenoids and flippers were always on.  Turned out to be a faulty 7402. 

I did a shop job, and removed the mylar...  BIG mistake.  The removal pulled the paint off some of the inserts and some paint off the playfield.

The backglass was flawless.  The cabinet was OK but could have used some touch-ups. 

Sold locally March 2005.
