    SOLD BALLY MOTORDOME PROJECT

    SOLD SOLD SOLD SOLD SOLD SOLD SOLD SOLD $400 I bought this game a year and a half ago. It was playable when I bought it, but it’s been folded up for the past year. I started to shop the playfield, but lost interest part way through. The upper flipper assembly is still disassembled, but I have...

    Yesterday, my lower right flipper developed a serious weakness problem. A perfectly shot left orbit couldn't even make it half way around. Here's how it looked: The first thing I tested was the end of stroke (EOS) switches. They were all working fine. Second thing I tried was swapping the...

    Oh yeah, I forgot to say thanks to Spiro Agnew for sending me the parts!

    The next step was to replace the melted GI connector on the Power Driver Board. This connector sends the power to the back box GI. As you can see, J120 got hot enough to melt the connector into two pieces: This is the back side of the board: With the help of my handy solder pump, I removed...

    So, last night, STTNG developed the ol' flutter/double flip problem: The flipper flips twice, and was unable to cradle the ball. The upper flipper was unaffected, and could hold, no problem. This ruled out a problem with an opto board. To be safe I swapped the left and right flipper optos...

    Tim's STTNG thread

    Today I'm investigating why my upper flipper almost never makes the shot all the way around the left orbit... even when the shot is perfect. The Picard Maneuver just can't be made. I took the glass of and poked around the flippers. I've noticed the left flipper, when raised, doesn't react well...

    Tim's STTNG thread

    So, I've been slacking on posting updates... **SPOILER ALERT** The game totally plays now! On top of having 5V issues on the power driver board, it turns out the MPU was grumpy, too. I was getting fuse errors, even though the fuses were fine. Also, leaking batteries wreaked a little more...

    This was still on the bench, BTW... when I put it back in the game is when I have no 5V

    A bit of an update. My PS's 5v gave me a solid 5v with no load, but when I took a reading from the board it was 4.3v. So I turned up the pot until I hit 5v. The board now reacted mostly as it should. Now I realize there isn't 5v getting to the CPU at all. So now I've got to follow things back...

    What's crazy is, I believe R911 and STTNG were released the same year. What a contrast between the two!

    Tim's STTNG thread

    Haha yup, it's been a while. I've had quite a few pins roll through since my last thread, I felt like a slacker! (see what I did there?) Yeah, R911 was my last/only pin that was a DMD. I felt it was time to treat myself. :P P.S., say hi to Jen for me!

    I was doing a little reading this morning, and realized something. The right side gun is spun all the way to to the left: Here's what it says in the CPU error section: I can't help but feel like I'm getting closer! Unfortunately I have to spend today and tomorrow at work, so there won't be...

    The playfield is very nice on this one! It's been in my boss's basement for some time, getting relatively very little play. I haven't looked too closely at them, but i am pretty sure I don't even have to change any rubbers.!

    Tim's STTNG thread

    I've never bench tested a board before, so I figure now is as good a time as any. PinWiki suggests using either a PC power supply (PS from here on), or an arcade PS. I just happen to have a 60-in-1 cocktail machine that I am working on, so I poached the PS out of it. As per PinWIKI: All three...
