Mauzy:
WOW. I must say, I'm impressed! That's a lot of crap to sift through. Kudos and congrats!
Kevin Mullins:
No kidding...... I only wish I could get to that level of diagnostics.
Still learning, but that addressing an clock stuff would have thrown me for sure.
Well done !! :cheers:
Looking forward to further progress.

The clock signal is the first thing we have to check. Without that the MPU never start. It's not so dificult to learn, but an osciloscope or logic probe is needed. ;)
After repair the MPU I fix some dusty switch's and bad lamp sockets.
Me, cleaning the playfield.
Shine, like brand new! ;D
Ready to play.
I playing. 8)

The right tools can definitely make any job easier! That play field looks great, btw.
Kevin Mullins:
Well, I have a cheap logic probe....... every now and again I'll break it out and poke around with it and watch all the pretty lights and listen to the beeps and buzzes.
;D
Now if I could just learn how to use it. :laugh2:
I enjoy seeing pins of this era come back to life. Something about them puts you into the game a bit more than the newer stuff. (in my opinion of course) Something deeper about the gameplay and sounds I guess.
