Is there a way to install a V-Hold pot? I couldn't seem to find one on mine. My pac-man board slowly scrolls vertically on this monitor. Matt

Just a quick follow up note.
On my 1084S, it's pot R225, "H-HOLD" and according to my DMM, it's 30K. I mounted a 25K pot (more than adequate) externally on the casing. Works well. I can't always get Tron to sync up, but I am also using boards that don't work 100%. Usually I can get close enough though.
I just ran a few lines through the plastic case and mounted it using a bracket and a small bit of prototyping board.

You didn't by chance see a similar pot labeled H-FREQ? I believe that's what it was labeled on the board itself.
Thanks for the link. If I have time, I'll see if I can set something up this weekend (going out of town on business so it may be a couple of days).

I agree, outside of sync problems, the monitor works great for vids. Let me know how it works as I'm interested too. Looking at the schematics I found (http://staff.washington.edu/rrcc/uwweb/1084P/):
Horiz. Sync, R437, 22K Vert. Sync, R331, 47K

This requires removing the case and finding the H.FREQ pot.. this is often near the front of the tube on the right (if you looked from the back).
I had this just happen with Tron (had to build a simple circuit to combine /H and /V sync too...).
I put everything back together and tested it with another JAMMA board (MKII) and it wouldn't sync. I'm thinking I'm just going to mount that pot on the case so that I don't have to keep pulling it apart. Anyone done that before? It's a tiny trim pot and I had this idea after I reassembled everything. Anyone know what the value of the pot is?
Otherwise using this monitor has been great.
