Picked this up yesterday.  Needs some board and connectors work, after resoldering all connector points, it will play, but has lots of random problems, especially with the switch matrix.  I can see that a few chips in the switch matrix have been replaced and the 40 pin connector definitely needs to be replaced.  Still in audit mode, but overall no worries, should come together well (famous last words!).  From what I've played, it looks fun, even in its dirty slow state.  Cab has lots of nicks and scratches, BG is taped at the bottom, black spray paint across one scratch (geesh!) but the rest of the BG (75%) is great, no flaking.
Kind of a rare bird, only 412 made.  It's very similar layout to Blackout, but made 2 years after Blackout.

Great find, look a nice project  

Good find.I like the long  lane guide going to the flippers.

DAMN!  Right in my backyard too!  Bastage!!!   Glad you snaged it and saved me a beat'n from the wife

That's a nice score. Once you get over the electronics issues with the old Williams, I think you will appreciate how they play vs, ahem, the wedgeheads.  

Good 'ol 40 pin, eh?
