A New Hope... "I knew you could do it!"
RetroACTIVE:
Good old mathbox problems are now a thing of the past! The board was failing tests 18 and 20D of the matrix processor tests. Turned out to be a bad LS165 of the 'A' register, IC 7A. I went and replaced all 4 (6A, 7A, 6B, 7B) of them as they were of the same date code.
Now I'm back on the monitor. It's too damned bright! I cannot turn it down enough. It's leaving green connecting vectors and a decent green dot in the center. I've read of a couple solutions...anyone had to deal with this?
"No reward is worth this."
RetroACTIVE:
Ok... You know that little adjustment on the HV unit called "SCREEN"?... that was it... derr. Maybe it would have been better if it were labeled "TRY THIS YOU F'N IMBECILE!"... nah not today...
I'm now waiting on the HV cage cover to help eliminate some screen "jitters".
I still could tweak the x-y analog board adjustments and I will but for now... I'm calling this done!
"The force will be with you.... always."

How do you get the roll pins out of the inner handles? I disassembled both handles, but can't slide off the inner part of the handles because of the damn roll pins. :banghead:

Actually mine had no roll pins... only set screws. Must be a different rev.

Mine has the roll pins but they sure didn't prevent the covers from coming loose of the handles. You did loosen the screws on the inside of the handles that hold the covers right (since we're talking obvious things here anyway ;) ) ?
Or do you mean these:
Just read about this on the Jamma+ forum. My handles don't have that extra hole !
RetroACTIVE:
My yoke does not have a 3rd hole as shown in Level42's pic. It only has the two larger ones for the set screws.
The funny thing is the axle does not even have an indent or a hole to receive the pin... and the documentation illustrates at least one set screw and one pin.

Yep, those are the ones. I just bought the tool to punch the pins out, but haven't tried it yet.
