So yesterday I got to tinker around with my Omega Race UR, and here's where I am:
1. I have 2 PCBs, and 2 power supply boards. When using either PCB or either power supply board, when I power up the machine, I briefly get the red LED on the main PCB lighting up, but it shuts off shortly after. Usually it's because the slow blow fuse on the power supply board has burned up.
2. when hooking up the main PCB, I first hooked up the edge connector as well as the 2 bottom connectors (a 3-pin and another one which I think is a 6-pin going off of my memory) and powered it up, resulting in what I typed in #1 above. I even tried replacing the fuse on the power supply board (whichever one I had in at that point) and hooking ONLY the 2 bottom connectors up on the main PCB (no edge connector), and the result was the same.
3. I wanted to check the connectors to see what voltages were getting to the main PCB, but I couldn't find a blasted ground tab anywhere on the main PCB to use (how I wish this was made by Atari), and reading the schematics for this game basically gave me a headache.
Additional points I noticed:
1. although I'm not getting anything on the screen, I did notice the red LED on the monitor chassis is on.
2. I can't get anything different to happen when the test switch is set to either option.
Any thoughts or input would be greatly appreciated! I want to see this thing live on!
