While I'm still quite green overall, I am not THAT green. I'm getting 4.98-4.99 at the boardset.

Where at the boardset? Track it through the boards. You should be able to test it on each of them. Getting 4.99 at the main entry point doesn't mean you get 4.99 later on down the line.

The way I read the instructions, the self-test is telling you that you have errors in the 5 divider tests listed. For each test is it listing the dip-switch setting, expected results and the actual result.
So now (again from they way I read it) you are supposed to:
Set the self-test switch on.
Ground the DIAGN test point on the Main PCB.
Set the option switches at 10D on the Main PCB to the the first test.
*Note that the NNNNFFFF is reversed, so it is referencing switch numbers 87654321
Momentarily ground the RESET test point on the Main PCB
If you do this, it should display the number of the test on the display. If you set an incorrect switch detting at 10D all three Main PCB LEDs will flash on and off simultaneously about once per second.
What does it display if you perform this for each of the five tests shown above?

i vote for cranking up the 5v to 5.2...

What about Dick Millikan out near me for board repair? He does all the other Atari Vectors, I don't see why he wouldn't do teh War of Stars... Do you have his contact information?
Up the +5v up to about 5.2V
I've seen all kinds of hell break loose when the board has bad mathbox PROMs (those 4 in a row small socketed IC's on the mainboard).

Would it be advisable to just shotgun the four? Pricey?

Having stressed out over a SW board set recently I can tell you what I found. And yes I was getting mathbox errors.
1. I run the +5 at +5.08, when it was lower I would loose background graphics once in awhile.
2. The game would shut down after being on for 5 min. then restart. This turned out to be a bad CPU.
When I ran the self test I had mathbox errors until I cranked up the +5 the highest I would set it would be 5.10 at the point entering the PCB.

If it makes you feel better, I've only played two games on mine since I got it. Still not working!

Trust me... that doesn't make me feel better... the exact opposite.

I'll mess with the voltages today and see what comes of it.

People tend to underestimate the importance of correct voltage. It's always the first thing i do to make sure its good and to make sure more damage isnt done to a board. You could waste a ton of time and money troubleshooting and replacing boards and parts when all you needed was a little adjustment on the power supply. Just my .02

Welp, it was worth a try I guess... but bumping the voltage up to 5.2v did nothing at all. Same issues exactly... same error exactly.

Hi - FrizzleFried - i am having the same issue with my SW - mathbox errors and tie fighters are all overdrawn.
Did you ever resolve this issue / get it working? If so, how? THanks.

zombie thread bump... but I just had the EXACT same tests results and fixed it by replacing one of the chips in the dividend latch (a 74LS374 at 4L on the main PCB)
