I just purchased an centipede to millipede adapter from Arcade Shop. I installed it and a working Millipede board into my Centipede cab. The picture comes up, but the synch is off, so that the screen rolls horizontally/side-to-side (this does not happen when the Centipede board is connected). The cab is using a GO7 monitor and the video feed into it from the Centipede board is separated into separate positive and horizontal synch feeds. I have tried moving the video input wires to the negative synch posts on the monitor just get a garbled screen. I know this should be an easy fix. What am I missing???
 
Yep and have tried every combination of video synch wiring that I can think of (neg composite, pos composite, neg separated, pos separated), still getting the screen roll (when the picture is visible.
 
Still having issues with this game. I did a G07 pot replacement with a kit from Bob Roberts and still have vertical scrolling issues. Also tried to swap out another G07 (the only other vertically mounted monitor I currently have on hand) and it showed the same issue. The scrolling only occurs when I hook up the Millipede board (with Braze Multipede mod) to my Centipede cab. When the Centipede board is hooked up there is ZERO scrolling.

Someone mentioned that G07's simply don't work well with some games. Do I need to get a different type of monitor? Has anyone else out there experienced problems using a G07 with a Centi to Millipede adapter or Braze Multipede kit? Would REALLY like to get this cab running with both Centi & Milli so any suggestions would be greatly appreciated.

Thanks in advance.
 
Does anything change when you adjust the sync pot? The g07s have really crappy and easily broken pots... Might be the pot itself is broken. I have never had a problem with the g07s themselves besides broken pots..sand I run a millipede in a centipede cabinet with the arcade shop adaptor. I also use that cab to test millipedes and centipedes after I fix them
 
Seems pretty unlikely you've got a monitor problem, i'd check the wiring - how do the monitor sync lines map through the adapter? I have the same problem with my Centipede cab and it's been so long I forget the details but I'm sure I narrowed it down to a wire mapping issue. There was a helpful RGVAC post about it as well.
