Anyone have one?

I was wondering if anyone had the Midway Off road challenge manual, or know where I can find it. I have been able to find the Ivan Stewart's, but no the Midway one.

Oh ok. I did check voltage again, and it is good everywhere but the security chip is still at 4.19. Do you think this matters at all?

Yeah I have, and I can verify that the pin 6 on all sockets are the same. Also is it suppose to save anything when I turn if off with the switch on top, because it doesn't. And when I test mode, is it suppose to reset everytime, or go right back to game?

Is there a way to check the socket? I check for continuity before and it showed good. I also looked for any cracked traces and didn't see any either.

Update: I got the chips in today. The game turns on and when it checks the roms, the U25 is still red and is showing bad. Is there another way to check that? Anyways, the game plays fine now, except when I try play the advanced boards. The first advanced board plays but I am driving through the...

Well, I'm not much of the chip Dr. That isn't very easy, those little legs are tiny, and its hard to get right on a good spot. So I plan on going ahead and ordering a new security chip. Could the reason I was getting a low reading on the security chip be because it was bad? I tested a bunch of...

Yeah, I had already checked it against different sockets throughout the board. It is the same on all of them. If they are assigned, and the one I have is dead, or even the wrong chip, how is someone going to know what to program on a new one? I haven't fixed the security chip yet, I don't know...

OK, checked the continuity on it, it looked good, beeped at every hole, except the 6th from the bottom. But I went ahead and tested the rest of them, and they all beeped except for the 6th from the bottom so I assume that's right. Was I suppose to have power on when I checked it? I was a little...

Ok, the number on the roms is M27C801. So I can use the multimeter to check for continutiy right? I would just take the rom out of the U25 and say the one right next to it, and test hole #1 on both, then hole #2 on both and so on right? The U29 doesn't even show up on the test screen. For some...

Yeah I am planning on getting a new security chip as long as I don't need a whole new board. That's basically what I am trying to figure out is if I need a new board. But so far I feel that I have made progress as when I first got it, nothing worked. Yes some of them do have the hologram window...

Yeah I cleaned them last night and put it back in today. Yeah I did the U25, I also have another one in U29 that's not showing at all, but with all the boards I have seen online, no one had a chip in there. So I tried to swap the chip from U29 into U25 and it didn't work either. Could i saw a...

Well, I cleaned all Roms that weren't soldered down. I decided to try it today, just to see if any difference. I just put board in without security chip, it was same old thing. Decided to try putting security chip in with leg still missing just to see. I noticed colors which I hadn't before, so...

Ok, I was talking about the R733 strip. It looks brown, maybe I will try to get a better pic of it. I will try the sandpaper to clean then. Thanks

Does this look ok? Or is it something that could be causing my isses? Also is it ok to take the battery out to look at it? Could it be bade? Also what is best wat to clean legs on chips?
