Hey guys. Joined the club yesterday with a project machine. I’m so excited to get started. Brought home a good example of an early production game with white caps. Playfield is a bit worn but not horrible. Backglass has some peeling paint. The game is completely disassembled. The cabinet is empty except the powered board and transformer. It came with a bin full of parts. Looks like everything is there. More importantly the package included a new CPR Playfield and shay backglass. Cabinet and head are decent. At some point will likely strip and paint them but the initial phase will be to clean everything up and restore all the guts, swap the Playfield , get it running and then play the hell out of it for a while. Thanks pinsider Cheddar for everything!

A few pics. You can see the side of the head where someone added some cream paint over the original. A little ME and alcohol pulls that up without disturbing the paint underneath.

And coin door restoration starts the process.

Thank thank you Mathazar. I thought about it but I was thinking there are plenty of similar threads and I’m just a home hobbyist average guy. I would like to do a thread so maybe your encouragement we’ll get me to do it.

Dave

Thank you Kris. Sounds like you are in full bore too. You ate the first chip and within months had the whole bag. . I think you have a good handle on things. I look forward the seeing your threads.

I took your suggestion and started a new thread to document the work..

Dave

I think your pf is better then mine.

Dave

Ha yes @yfz450. I saw that in the pic and wondered if anybody would know what it was. That’s my other main hobby. My brother and I are active Cowboy Shooters. (As well as target and some trap). I cast for everything we shoot.

Dave

Yeah. Impossible....been casting forever and have saved up for a rainy day.

Dave

Hey guys. Can somebody post a couple of close up pictures of the three flippers mechs showing the switch stacks as well as the wire color and placement. Mine are a bit jacked up and I’d like to see some clean original stuff.

Thanks

Dave

Coin switches are definitely something to focus on. Given that somebody made a change to that area (good bad or indifferent) it would be a good idea to disconnect them from the circuit to eliminate that possibility.

I am not at home now, but I can see schematics show J1 pins 13, 14, and 15 are all ground. Pins 13 and 14 are unused. J3 shows 5, 6, 19, and 20 are all ground and none of them are "used." Based on this I see your comments about one wire for ground on J1, pin 15.

Schematics show all these pins tied together, I assume by the board traces. I also remember noting that a board trace in the upper right hand corner passes under the mounting screw.

Last night I checked and the board mounting bracket is not grounded so the mounting doesn't add to the ground circuit.

What did you guys do to add more ground....?

I can see running a ground braid to under the mounting bracket and thus giving the traces that path?

Otherwise, run some wires (one to J1 and 2 to J3?) to the unused pins and then back into the harness to a common ground location or the braid?

Dave

Interesting. Definitely sounds like great redundant routes. I did something similar using ground braid screwed into the aux board bracket and across to the hinge screw and back box ground shield.

I will also look into adding more ground routes for the main lamp board.

Dave

Sounds like adding an additional ground path to the aux bracket is the smart thing to do.

Dave

Duplicate post to my dedicated restoration thread but I figured I would add it here also.

Here we go... first time I tried to fire it up was when I noticed I was missing u9 and u11. It took about 10 days to get those and on boot up found that u8 was bad. I ordered the nvram replacement and that arrived today..

Installed and... we have life. ! There are still things to sort out but we are where we need to be. The volume pot seems to be flaky but the audio is strong and clear. The are little gremlins here and there but I have managed to play a bunch of full games on it...

Another one is brought back from the dead...

One of the displays was bad and I pulled it. I swapped it in the place of another, reflowed the header pins put it in and they both work fine.

Dave

I didn’t notice that. (So excited it makes any noises). The underside of the pf is high on my list. I have new one to swap in so I hope to sort out most of that stuff then. I have a feeling that there are some bad and misaligned switches.

Dave

Does this help?

One more. Always better to get a couple of angles.
