Thats a good question. I see the battery on this- and I wouldn't say it looked new by any means. I'm going to change it out when i get back to that project. But it'd be great if someone could verify whether it was a suicide batt or not.

Hi,
I've also got an Off Road arcade machine with a similar problem: When I turn it on I get garbage on the screen and can't go any further.
When I press the right buttons, I can go into the diagnostic menu and run most tests successfully (seeing the backgrounds, hearing the music, testing the controls). So far the only thing that looks wrong is that I get a slave communications error.
Since this thread hasn't been updated in a while I am wondering if anyone was sucessful in getting any further with getting their machine working?

Nope, still a "rainy day" project for me. This one is still on the back burner. Here in NE Ohio we are getting ready for 6 long months of bad weather, I'm guessing I'll pick this one back up sometime soon. Have you tried resetting the socketed chips? Probably won't help but worth a try.........

We've got a long winter ahead of us in Canada too, but I have a bit of a deadline on this project as there's a $100 bet (2x what we bought it for) saying we won't be able to get it working by December 1st. The challenge is that it's in my office so I only have a small amount of time to fix it during lunch, though lots of time to think about what I should be doing the rest of the time...
I was thinking of:
(a) trying to remove the coin molex connectors (it something about that in the manual)
(b) clipping the battery -- it surely must be dead
(c) reseating all the IC's as you suggested
[when we first bought it we saw one pin that was out its the socket, and found another IC that had been replaced and had a broken lead]
(d) following advice on http://arcarc.xmission.com/PDF_Arcade_Manuals_and_Schematics/Double_Play.pdf
Which says what I should check these on a slave communications error:
U19 - socket - 74LS374
U21 - socket - 74LS374
U22 - 74LS461 or 74LS374
U23 – 74LS461 or 74LS374
U45 – 74LS461 or 74LS174
U60 – 74LS461
U62 – 74LS374
U64 – 74LS374 or 7533
One of the challenges, that you can see from the above, is that I don't even know what chips are in those locations as service manual shows different things on different pages. Guess I'll find out on monday...

That manual seems pretty straight forward. Just start hopping through them one by one. I don't think those are that expensive (the ic's)... and a few of them are socketed. Just order a few of each chip in case you screw it up, then slowly replace them 1 by 1.

Keep us posted.....
I have 2 crap boards.....I plan on swapping out each socketed chip one by one. This of course assumes the same thing isn't shot on both.....
Anyone ever swap that battery out? That thing worries me.....

Is there any way to verify its a 2 player or 3 player board? I want to get one but don't want to buy the wrong one.
Thanks

The boards are identical and can be changed with new ROMs. I believe the only way to tell the difference are the labels on the ROMs.
Super Off Road Noob Question
I just picked an Super Off Road with the track pack. At first it would boot up to garbage (scrambled image), but after a bit, it booted up and looks beautiful. Even played properly, which was a blast.
Then I got only one small problem-- the backgrounds are all off. Instead of the racing background being aligned properly to fill the screen, the background only fills the top half of the screen. It's like you took the screen and shifted it to the top half of the screen.
The cars still naturally follow the path as it should be (even though you can't see it) So now it's a little hard to play.
Diagnostics all check out. No RAM, ROM, slave or video problems. When I do a test of the backgrounds, they all look and test out properly. That's weird. If only they'd present that way on the screen.
It doesn't look like the boards have been messed with. I opened the back and pressed each chip in to see if heat creep had loosened them. Put it back together and powered it up- same background problem. All diagnostics checked out.
As a noob, I am open to any all suggestions.
Thanks much

I found a thread with the same problem I have:
http://forums.arcade-museum.com/showthread.php?t=19665&highlight=super+road
I should have searched a little harder, but I'm not clear on which chip.
Since it's a Track-Pack machine, I don't think I'd need to switch it to a regular Super Off Road as described in that thread. (Since my machine was working fine earlier)
??
Thanks in advance

Thought I would revive this thread a bit with my issues.
2 bad boards. 1 Track Pack, 1 Normal.
Normal Board.
Diagnostics - Audio Processor not responding.
Game loads up fine and demo plays fine. When I go into a game it pauses every 1-2 seconds for about 5 seconds. When I turn sound on for Demo it does the same thing.
Track Back
The dreaded white garbled screen, no diag, sound or anything.
I tried swapping the top and bottom boards with each other just to see if I could learn anything.
Track Pack bottom - Normal Top
Still white screen. This tells me the bottom board is actually the problem?
Normal top - Track Pack Bottom
Just boots up to a garbled, colored screen. I assume some issues with the ROMS here.
I would LOVE to get one of these working since the machine is all cleaned up and ready to go.

I will be out of town until Monday, but then I will

Well, Ill update with my woes on this.
Bought a 2nd Track Pac board, so no I have 2. Both show the same garbled white screen as soon as the machine is turned on. I can get to no diagnostic type screens. Have swapped boards, no luck.
If anyone knew how to fix these boards- they would sure have some business for a bit. And if they got one board working for me, they can keep my second one to help others, and Im sure there are a few others in that boat too.

Well I think I am going to go back to my shop and swap all the chips rom chips from my non track pack to my track pack and see what happens.
Not that it will help any of us fix the problem, but maybe it will give some insight.

Well, no luck.
I swapped every removeable IC from one board to the other. Track Pack board still gives me the white screen and the non track back just gives me a garbled colored screen now. LOL.
Anyway, I am going to swap chips back and hope someone figures this out. It's weird that the problem seems to be mostly on the track pack boards.

Just thought I would check in and see if anyone has had any luck with this or even working on the issue?
I've got my board on my test bench. Not sure where to begin.
Thought I would pull all the roms and see if it boots with the same issue. If so, I can we can say it's not a rom issue.

Guess I will add a little more information. Not sure if anyone but me is following this anymore but figure I will just keep adding bits of info in case it help.
I hooked up my track pack board to my test bench that runs a RGB to VGA converter. Created a video and power harness and fired it up, would get the same white screen then just no signal from the converter.

I'm following,
I now have 3 bad boards, 1 working, and 1 semi working.........
This has been a rainy day project for me for a LONG time now.
I spent a little time working on it this past weekend with no luck.....
If I make any progress I will post here.

I have two non working board sets as well. Hoping for a breakthrough here soon!
