I have almost finished a new Nucore install in my RFM, and now that I have the PC running, my image on the CRT is offset slightly to the left (I already fixed a resolution problem, that I will post about separately, along with the other issues I ran into and solved along the way). The pot switches don't fix the issue, and I saw a few posts that say this issue can be fixed by pushing the "sync" button on the Wells Gardner monitor. The problem is that I don't know where this button is physically located. Can anyone please describe, or better yet, take a picture? Is it at the top, or on the back, or elsewhere? I don't like mucking around near high voltage, so if anyone can point me in the right direction, I'd really appreciate it! Thanks in advance.

That sounds promising, but now I'm going to ask the stupid question -- can you please tell me - exactly - where it is? I can't find anything that appears to be a toggle switch or a button. I'm sure I'm looking right past it or over it. I have no problem finding the remote pot switches, and I can see the other pots at the "top" of the tube, near the neck. There is a circuit board on the "back" of the tube too, but I did not see a switch, when looking at it from the sides of the rear backbox. I also don't see anything from the front (behind the translite). Again, possibly because I don't know what I am looking for. I appreciate any guidance that you can give as to how to access this switch!

Thanks - any tips on how to (safely) access the mainboard?

Thanks for the concern, and i normally agree - better safe than sorry. But tonight, I took a picture with of my board with my cellphone, and finally saw the button (it is more like a button than a switch on mine). I was able to push it in, and sure enough - picture centered! It's slightly narrow (wish I could expand the horizontal like the vertical), but the shots line up perfectly. Happy to report that my new Nucore system works 100%. Now, I can strip the PF and clean it up. Thanks for the replies!

WhiskeyTango - Do you know how to program the pubcard? I have one, but have no idea how to load Applejuice's 2.0+ versions on it, and cannot seem to find any instructions/tutorials for this? If you know, and are willing to share, would be much appreciated.

Also, I too have some microswitches to replace. Is there any consensus on which replacements to use? I've seen references to cherrys, db3s, etc. -- looking for the best plug-and-play option, with least future maintenance headaches (assuming such a thing exists in pinball...

Helpful info on the swithces - order in, and many thanks.

However, I must be missing something on the PUB update process. I've perused the PUB update files on the Planetary Pinball site, and the pub update files are locked to the official versions of the software. I do not see a generic "PUB updater" file, which I could use to load Applejuice's software. Am I missing something? I feel like the tools are staring me in the face, but I can't figure out how to make them work together! Any help is appreciated.
