Hello group! Never owned a System 3, so I'm going to have to learn.

Got a Bell Ringer (just for fun at local shows!). It had no Control Board, Ebay Boston Pinball came through. Had a friend burn a Bell Ringer ROM and powered up the game.

I'm stuck here as I cannot figure out if this a ROM error or a diagnostics code. (It also flashes "Break") I cannot get into the test mode from the one switch inside the right of the coin door ( there is no elaborate Test/Tournament/Volume board to the left).

I do have the manual from PBR and can look up things if necessary. And yes I have seen the Pinwiki on System 3, but am stuck right now.

Hints are appreciated thank you!

Hmmm, no hints by all you experts?

mbaumle Thank you very much for the detailed help!

You are right on the mark with this. The NVRAM installed is indeed a 6264 chip: https://www.marcospecialties.com/pinball-parts/RAMTRON
The board that I have from Boston Pinball is a Revision 5, so I need to contact them to see if I can get the version of the board that will work with Bell Ringer.

Again, thank you!

Also thanks.

I did contact Boston Pinball and am working with him on the solution. As I find out something, I will post it here to help the group.

I am a little confused as I am supposed to do a System Reset - Factory Defaults on the machine. As Bell Ringer only has the one test button, I have pressed it and cannot get into the System Diagnostics. That is the only way I can reset the machine, correct?

The Reset buttons on the Control board and the Sound board do nothing to change my issues.

A little more detail with Bell Ringer. A friend of mine has a Vegas, so we kept the ROMs and swapped A1 Control Boards. Bell Ringer came up with the older Control Board from Vegas with the 6116 RAM. I have a working game now with the original Vegas board.

The Boston board and the Vegas ROM in my friend's Vegas machine kept going Beep, Loop, Beep. Unable to enter test mode and just keep rebooting. His game was working before the board swap. So I suspect that the Boston board might be not working. I am in contact with Boston Pinball to give him all these updates.

Ah no. Not completely working yet.

Hoping to bring it to PAGG however. You can do your wagering on that little machine!

And to figure out the Test Mode on this System 3, that one Test Button goes right into the Test Menu with the working board.

But of course, all you System 3 experts already knew that!

Update to my Bell Ringer issues: Jim did come through and sent a replacement board. This board worked!

mbaumle it looks like the same revision (5) as the other board. I placed the 27512 ROM with the BR code on it (left the jumper at 512) and everything is booting so far. I have other issues with the game not kicking up the ball when the credit button is pressed (set on Free Play), but hope to have these solved as I work with someone local next week.

I appreciate all the help from the group here!
