Just got a Star Trek Voyager w/ missing monitor.
Also have a CGA/EGA/YUV to VGA Arcade HD-Converter PCB (GBS-8220) from a DKJR project I haven't started.
Ok. I got the machine running.
The hard drive was toast; but strangely the Battery was ok.
I reimaged a 120GB WD ATA100 drive from CHD.
I have the machine booting into Linux / Xwindows... and the game launches. The switches / gun switches are working (according to switch test).
However, there is no video output from the Jamma adapter.
I think I hooked it up correctly; but the adapter is saying no signal.
If I connect directly to the VGA connector; the game/video is there.
So; Here's what I determined from the jamma harness:

STV = GBS-8220
Yellow/Red (pin 1) = R (P11 pin R)
Yellow/Green (pin 2) = G (P11 pin G)
Yellow/Blue (pin 3) = B (P11 pin B)
Yellow/Black (pin 8) = GND (P11 GND)
Yellow/White (pin 10) = V Sync (P11 VS)
I tied the 5VDC for the converter to a 4pin molex from the PC PSU.
Suggestions?
