Re: Gottlieb System 3 Freddy Constantly Reboots

The U11 swap will be less expensive than replacing the ROM's providing you can do the work yourself. Get the chip(or two) and a few sockets. Practice desoldering and soldering on a junk board first if you've never done this before. You also need the correct soldering equipment.
If the chip doesn't fix it then new software should. From what I know Gottlieb was aware of the problem with programming/U11 resets and fixed it in later revisions.
PBR has the ROM images but someone here may have them saved as well. I don't have them for Freddy.

Why would an old version of software make a difference. Wouldn't it have always run with the software and the hardware has not been updated? (Asking as a software developer.)

It looks like the chip is 45 cents at GPE. Hopefully it can be that simple?

I assume there are people on the board that could burn new software chips for the game? Do you know about how much and from whom? Or if you or anyone else can provide this service it is probably worth having anyway.

Thanks

Thanks for the info.

The slam switch is not stuck.

I turned on the machine just now. It was showing about 5.2 VDC. I slightly moved the voltage down to 4.9 then up to 5.3. It did not reboot. Yesterday it did and I am afraid that I could have or will screw it up more than I should.

I do not have the manual yet (ordered yesterday from PBR). I am not sure what the 123 chip is or where it is.

Someone told me that my battery could be dead. But yesterday when I changed the number of balls from 3 to 5 it seemed to remember that between getting the machine back working.

I tested the voltage on the battery from ground to the battery. It reads 3.31 VDC. I am not sure if this is a useful measurement. Should I try to replace the battery? What should the voltage read?

Someone else told me that I should get a different cable to the power supply that will boost up the power.

Does any of this make sense to do?

I hope replacing the 123 chip is something I can do without sending it out to a board repair shop?

Thanks
Michael

The "123" chip is a 74HC123 and is located on the control board at U11. That may be the problem or it could be running on an old revision of software and may just need to be updated with the current rom revision.
