Ok going to send you a PM

Try using the ribbon cable out of the Getaway, it is the one with the 4 connection points.

Take John up on a new ROM, has to be it if all the boards & mechanics are good

Yeah, take John up on the new rom at this point.. Other than that you could have a bad CPU chip socket.. I cannot think of anything else.

Cannot hurt to try.

Is the claw moving now left to right/right to left as you turn on the game or during gameplay?
Just wondering if the elevator magnet is the only issue right now.

Well, you have tried new boards, different ribbon cables, different roms, and we know the magnet is good... I am now officially stumped. The only possible thing I can think of is the socket the rom goes into... could be a scratched trace under it, I would take out the CPU, remove the rom and take a good look at the socket.. I think your Getaway uses the same MPU board... just for the sake of ruling it out, try the CPU from Getaway in Demo with the new rom you got.. If that does not do it, I am out of ideas...

Also check all the solder on the back of the CPU, see if anything looks suspicious, any solder joints that look questionable.. Switching the CPU board should be the next step, could be a bad pin going to the driver board, could be a bad rom socket, last thing I can suggest.

It is all I have left in my bag of tricks.. I cannot imagine what else it could be... the real stumper in this is the fact the magnet works with that one rom, but not an original rom... so weird. At least the CPU is easy to swap.

Any updates?

Going to try the CPU swap?

Please post how it goes, I have been with you alongside for a while on this one...

You should be fine.

Not weird at all. Remember that Demo Time was (I believe) made using FreeWPC, which doesn't contain any factory code whatsoever, it is a ground up reimplementation. This means that it may have different requirements for the claw to work, for example the code for driving the switches may be more tolerant of a faulty opto, may work with optos that have failed etc etc.

Really curious to see what the problem is with this one. Might be worth updating your first post with everything you've tried so the information is all in one place.

In a previous post, I had mentioned the same thing about the code, and that the OP contact the guy who made the code and check with him in reference to whether or not that was the case. He has no failed opto's we went down that road, he swapped the aux driver board and the fliptronic board, new ribbon cables, check all fuses, and we know the wires are good to the magnet as it works with the demo time code.. my last thought was a problem on the CPU board, specifically the socket he has pulled the rom from several times and tried other roms, my last suggestion was to try the CPU from Getaway. We pretty much have gone though everything, including several roms...

HA!!!!!!!!!!! Finally!!!!!!!!!!!!!!!!!!! You can put the board in your getaway and see if you encounter any issues with the Getaway, if everything works then you are fine. Really go though the Getaway, test solenoids, switches, etc.. everything..

I thought you would be more excited to see it work?

Your demo man board has 3 holes where the chip is installed that look like then need more solder, if you look at the bottom side of the chip socket, you can see on the far left there is 1 that looks like it needs some, the next looks good and the last 2 look like they need some.. also check each pin the chip goes into, sometimes one of those gets corroded, or bent. As far as the ribbon cables they are fine that way

Way to hang in there til the end Balboa...very generous sharing of your time to help out the OP, job well done

Thank you cosmo, I appreciate that!

Demo man was working because the code was set up different on that Demo time code, as I stated before, I am sure the code was set up differently than the original code to make the claw work it may have used a different pin to control the claw or something, in your case, something is wrong with the CPU board, I still think that socket, but I could be wrong... do not attempt to solder yourself after what you mentioned, send the CPU board to John Wart, or Chris Hibbler, or K's arcade or Boryguard, or coin op cauldron or anyone else who does board repair, you need that CPU checked out. If you don't want to go that route, check out K's arcade for a replacement rottendog board for 179, the repair would be cheaper and the better way to go..

Again, NOT THE BOARD FOR YOU TO SOLDER if that was your first time soldering, send it out, get it done right!!

I am seriously considering going to Allentown, trying to find someone to go with me, I hate making that drive alone. What days are you going?

I know pinfest the show near me had a great board repair guy there doing repairs at the show, does Allentown have someone doing board repairs there? If so, you could bring your CPU there. But like I had mentioned you could try it in Getaway and see if everything works.

If I go, I would go Fri as well, want to get there when there is more stuff available.

Looks like I will be there Fri... as long as my buddy does not bail out on me!

Hey, if it works, it works. Just go and do a solenoid test on Getaway, and see if all work, if they do, you should still be good. Yes, that would do it, it does not take much to ruin a trace like that. But perhaps you will get lucky and that pin will not be a factor on Getaway...

I am pretty sure it can be fixed if it comes to it, you will not end up buying a new board. But let's hope is just works perfect in Getaway, and you can relax and play them!

At least the Demo mystery is SOLVED... that is HUGE!
