Progress!Yesterday when I got home, the Jamma harness was in the mailbox (yay!). Had to cut off the molex connector for the video and solder on the one from the monitor, 5 minutes. Started looking at the harness and realized that I need to brush up on my Japanese, apparently Paradise Arcade understands this language better than I. Back on track, figured out which way was what on the harness, connected it up to the JPAC. After 3 hours of *^$#ing around with the video, resolution, etc., I have this:

Let me tell you, this was a pain in the --I'm attempting to get by the auto-censor and should be beaten after I re-read the rules--. I am still seeing something weird. Since I had my LCD attached to the DVI port of the video card (Radeon X1600 Pro) and the JPAC connected to the VGA port, the video displays on the arcade monitor just fine (@ 320x240 32 colors). When I disconnected the LCD via the DVI port and even disabled the screen in the display properties of Windows, the arcade monitor won't come on. Plug the LCD back in (still disabled) and the arcade monitor works flawlessly...

so..at that point I was pretty tired 10:30pm and had to be up at 03:30 this am.. I'll have to play with this more.
Monitor Calibration Question: If anyone is using an arcade monitor with the 320x240 resolution, what on earth are you using to calibrate the colors? Guess connect, re-enable LCD and get something over to the other screen? The resolution is so horrible for Windows, that it really renders a keyboard just about useless... Which reminds me, that cool slide out keyboard tray may very well just come out, I can't see any reason for one on these things. I hadn't expected to network this PC, but it appears i'll be tossing in a wireless card for VNC'ing into it (remote).
