Hello everyone, just joined the club last week. Hoping someone can look at the pic of the back glass lighting and tell me if the splices are normal. Also what bulbs are supposed to go in the black holders?

Thank you sevenrites!! I'm sure I'll be asking for more help as I dig in and ship the machine.

Has anyone used a SmartDMD or DMD Extender on Gofers? I've searched but came up with only Color DMD. I would like to make a larger display is possible, which is why I'm asking about the DMD Extender options.

Starting to get an order together for a shop job and realized that I need to remount the left and right flash lamp assemblies - they just aren't mounted right... Does anyone know what size spacer posts go where? Can't find it in the manual.

Also, I found these wire taps on the line to the middle spotlight on the right ramp. I can't imagine this is normal, but figured I'd ask before tracing through the harness.

Quoted from evh347:

Taking the gofers apart is not that bad. Just take a few pictures. Honestly, the best tips I can give you is give yourself plenty of light, a magnetic tray to place your screws/nuts as you remove them, and use a magnetic tipped nut driver. Make sure your machine power is OFF. Another tip is to take breaks...I have found myself getting frustrated, losing my grip on an insignificant nut...and then I start shaking the machine (no balls installed) to get the nut to fall out into the bottom of the cabinet. Bad move...with the loose gofer, it came out and ripped all four connections to the two optos and I had to pull the solder iron out to fix that.
Really, when you're just starting out, take pictures and disassemble slowly. After 1-2 times, its easy to pull them out and reinstall. I can do it now in under 2 minutes and completely disassembled in 7 minutes.
NGG is my first pinball machine. I spend more time under the hood than I do playing it. It can be just as interesting figuring out how the whole thing works as it is playing it.

The #25 nut is a nyloc nut, and should only be used 1 or 2 times before it is replaced. They can also get old and brittle... It relies on the screw threads gripping into the plastic insert to keep it from falling off, not toque like a traditional nut in a metal joint. You can find them at most hardware stores and are worth the 30cents to just replace them next time your working on the machine.

So my back-box connector is hacked, could someone tell me if the backbox ever changes during gameplay? Mine is just always on with the 5 random flashers working. In test mode GI strings 4 & 5 don't seem to turn anything on/off, just wondering if the backbox is wired wrong and I should look into it.

Quoted from robm:

It is completely missing the backglass - wondering if anyone had a scan of the backglass or translite that i could get printed up - feel free to PM me if you do.

Mine is flaking bad on the edges, I too would be interested in a scan or print if anyone has one.

Could someone confirm the length of the post that mounts the upper playfield? I am replacing, and think mine is too short since it has a marks from the right gofer ramp hitting it.

#892 1 year ago

Yes, please measure the post. Has anyone used a washer our something to space up the mini playfield? I don't want to scratch the new one after waiting so long to replace it.

Quoted from Bugsy:

I am planning on buying an NVRAM for my game, but not sure which chip type to go with. I obviously know that NGG is a WPC-95 game, but on Pinitech's website, it says those type games "could use either a 62256 SRAM or 6264 SRAM". I have done other Williams games before and simply matched the number from the existing RAM on the game with the replacement I needed.

However, on my Gofers, the existing chip doesn't seem to list one or the other of 62256 or 6264. Anyone have an idea or recommendation for which NVRAM chip to purchase?

I choose not to NVRAM because I wasn't comfortable soldering in a socket. I did un-solder the battery holder from the board and install a remote one in the bottom behind the speaker.

I think you can add the GIOCD board, and program it to dim the back-box lighting once a game is started.

I'd have to check, but I thought NGG took 4 balls, not 6.

pinbuck Please check out the mini-playfield I have in the market place: https://pinside.com/pinball/market/classifieds/ad/58274

Swap out isn't hard, just takes some time. The whole upper assembly is actually only held on by one screw. My advice is to find the harnesses that go up there for the lights and switches and disconnect, and free those before you remove the screw. Once the single screw comes out, you pull it forward about an inch, and carefully maneuver it out between the ramps. Once removed, it is fairly simple to remove and transfer all the parts. A few wires need to be zip-tied to the bottom, but not tricky at all.

Schamattack awesome grab, I saw that on CL and almost thought of buying a second. If you need to do any comparison or need any pics let me know I'm right down the road in Oak Creek.

Quoted from dudah:

Can someone please post a photo of the wiring on the back of the backglass? I took mine off to clean and can't find the photo I took.

Not the best picture, and my wiring harness it hacked, but this may help you with lamp placement. All the black bodies should be 455 random flash bulbs.
