H everyone, i have a Baby Pacman i am desperately trying to get back to life. The one i got is missing the PCB light lamp board & as it has connectors in the middle, I assume this was a model which had that as opposed to the single lamp matrix.

First off, how can i 100% be sure that it is the PCB board version. I assume it is as it has connectors - but it also has screw holes in the PF where single lamps were. It looks incomplete though so it looks like a possible "aborted attempt"

There seems to be some mixed info out there to if i can convert a previous PCB version to be single lamps by manually replicating the wiring to one which used the single lamp matrix style.

If it was a PCB board version, my preference either way would be to keep it that way - sounds much more reliable. Would anyone know if there is one available anywhere - or if it would be possible for someone to help make me a replica based on these pictures. (i have posted a WTB ad already)

Being in Australia, these machines are super rare & most people have never seen one. I desperately want to get this one going to be in my collection, but also to "guest" in our many arcade bars etc. Its a gorgeous piece or Pinball-Arcade history and i really want one to be seen and played here. Any help i can get would be really appreciated.

These are some pics i found online of the board - would these be sufficient to help get a replica made?

be awesome if they did get remade somehow. I'd love to switch over from the socket edition to something cleaner looking like this. I've been looking on and off for years for it, or a spare playfield with one. To be honest your best bet is to try the baby pacman club thread... but chances are your probably going to have to go with the sockets. which means taking the wires out of the connectors and soldering them directly to the sockets.

The manual should hopefully have color codes for the wires.

I have been told that there are people out there who can re-make these if people scan them. Perhaps if enough of us exist we can get something like this to happen?

You can’t just swap them, the lamp matrix vs the PCB board have different connectors and you’d have to make an adapter for them to be interchangeable.

isn't it just one or two commons (all controlled GI) and a bunch of lamp light wires?
it'd be the same thing with sockets.

can't be that hard, unless there is something I'm missing. all you would have to do is use a meter to test continuity on the different points and make a connector accordingly, based on the wire color off the manual. I wouldn't want to interchange them once I have the PCB board.

People can, but it probably be easier if they had the board. So there is no mistaking which header pin goes to which trace and where. I don't remember the baby pac manual having the schematics for this lamp board.

My tech boffin thinks its pretty do-able. The board would be easier IF it was easier to actually find one, which at this stage - seems very uneasy.

As i know someone with a "lamp" version, I have also gotten them to provide HD pics of their lamp matrix wiring which can then be replicated.

My preference though is to find, or get a new board made if thats possible. the PCB board does a better job overall IMO

That board looks fairly easy to reproduce for anyone with board making experience.

You don't really need a schematic for it. Those images define the circuit although a physical sample is always best without a schematic to be able to verify everything. A physical sample is also needed to correctly place the mounting holes and/or pin headers.

From the dimensions it doesn't look like it will be "cheap".

I think the biggest challenges are:

  • Getting a physical sample.
  • Verifying the circuit is correct and true to original.
  • Verifying the mounting hole locations are correct and compatible.

I think your time frame (how quickly you want to be done with your project) will dictate which way you go in getting your machine working.

One thing i am is very patient. I have purchased a new CPR playfield & will be re-doing the clearcoat, so i have time on my side for sure.. Fortunately the machine is super pretty to look at even when its not working, so it still is paying for itself in the meantime with the smiles it gives me.

I will keep hunting for a 2nd hand one or try to find a way to perhaps get one made if all else fails. If there are others wanting one, PM me and let me know. If i find more than 1, I will let you know. If i end up going down the "re-make" path, we might be able to get a small run done if enough interest - will save on $$$, all-round

A friend recommend i try the VAPS website forum (Vintage Arcade Preservation Society ), apparently their forums are great for stuff like this. For me to get an account there though, i need to have a
1) have a recommendation from an existing forum member, moderator, or administrator. If you intend to ask a friend to recommend you, please ask them to look at our FAQ on recommending new forum users at: http://forums.arcade-museum.com/showthread.php?t=247149

Can anyone here, who is a member, possibly give me a reccommendation?
