Unpredictable and erratic behavior like that usually indicates a bad power problem. Unfortunately there's no ROM test for that as having a good power supply is a minimum requirement for running any CPU chip properly. Got to have enough blood in the veins so to speak. Do you still have the old CPU board? It would be interesting to find out exactly what the problem was with it.

Yeah, that's the funny part. I came to the same conclusion and bought a new swemmer power board first thing. I knew the power supply was in pretty good need of replacement/recap. The behavior was unchanged with the new power board though.

I kept the old CPU board. Not sure what to do with it though. Is there a good means of bench testing it? I know the pins and connector between my CPU and driver board were re-done not too long ago, so I don't suspect I have any issues there, would be a shame to not be able to use it after all that work.

This thread also shows some addtional info on the power issue:

I always keep my old boards for parts, or in the event that I may one day want to refurbish them. If you don't want to keep it, I'd be interested in testing it myself to see if I could find the problem.

Actually, I'm glad you linked that too. My big cap I'm thinking is also looking pretty old and I noticed unusual light dimming on my play field lamps during one of my games a few days ago...That fuse based bridge rectifier seems like a much better option than just swapping out the large cap

Hot damn that looks nice! I'm waiting on reproduction playfields to be run before I do too much to mine. Wish there was a way to know how close that list is from being filled...

Agree on all counts. That restoration looks fantastic!! And I'm also waiting on a CPR playfield to start a restoration. Love this game and it always brings me back to my childhood in the early 80's playing it at a local arcade.

Anyone have any update from CPR and the playfield run?

I’m dying to hear

Will buy one in a second if they are announced/released. I wonder how many “interests” they need before committing to build? Makes me want to commit to buy 2-3 just to get the one I need.

I think Gorgar is on the chopping block at my house, so I'm liable to drop out of the CPR interest list before it happens...

This was supposed to be my first game fully restored to new condition, but I need the space and the theme is a bit hard to explain to my toddler who is starting to become afraid of things. My daughter now understands the concept of "hurt", and it will be difficult to explain that Gorgar won't really hurt her even though he says that...

Ugh... I have to think about these kinds of things now...

Alternatively I guess you could just change the voice audio mix down to nothing :p

I was checking out the CPR Playfield website and it looks like Gorgar is in the preorder phase. Am I looking at it correctly? I thought they had previously just been gauging interest... but i sent an email with the preorder button and got an automatic reply telling me they would let me know when the time comes to pay for my order.

Is it finally here? Ok, realize the next phase still may take quite a while, but it feels closer at least.

I think it’s the same as it had been for a while? I’m not sure but it seems like it’s been stuck here a while.

Nope. It's the same just looks different because of the new web site. I like the old site better.

I noticed the price says $750. Seems like it was cheaper before. Guess we've been on preorder so long the price increases. Maybe I'm wrong. Anybody remember?

Thanks for clarifying that. Memory wasn't the best I'm sure, but I didn't realize it was at pre-order status before. And you're right... old site was a bit easier to navigate and figure out.

The more I think about it I'm sure the price wasn't $750. It did go up since the list started.

I have to look but I think it was $600'ish....... I've been on that list for over 2 years now and thinking about letting my Gorgar go its been so long....

Do you get the price it was when you signed up? I guess it can't really be proven, though... isn't part of signing up doing so under the conditions that you're willing to pay the price you see at the time you sign up?

I recall it being maybe 650 for pre-order and 699 after?

https://classicplayfields.com/shop/pinball-plastics/gorgarplastics/

Gorgar plastics now out of mothballs on the CPR website. As far as I could tell, these haven't been in stock at any of the usual suppliers for quite some time. Now just need to get that playfield into production and we will be all set!!

Oh no. I thought this was good news. I already have a Mayfair backglass and the CPR plastics waiting. Still stuck on playfield.

If you, or you know someone who does, have access to a chip burner and some EPROMs you can try these tests out. In particular the solenoids test will allow you fire each one at a time and by doing so you might be able to diagnose the problem.

There's a complete set there so you can test the whole machine, including the CMOS and RAM chips, which could also be suspect.

Here's where you can get details: http://pincoder.reversion.ca

let me know if you have any questions or need more help

I'm sure it's been brought u before, but...flipper upgrade? Can I use Space Shuttle setup? These things are weak...

Vid has a thread on upgrading Williams flippers with fliptronics mechs from pinball life. A+ would recommend.

I keep waiting until my eventual playfield swap before I switch mine. Guess I'll keep waiting >.>

I think we need to start a new club... “Waiting for Gorgar playfield Club”. I’d be a charter member for sure.

Right behind me.

I think we’d have lots of company. Unfortunately not enough to get CPR to move this to actual production yet.

I’m in the club finally

Play field please

Quick question for the club. What is a good adjustment for the flippers? If I align the flippers with the alignment holes, it makes it difficult to trap a ball against the flippers and the rails. If I adjust the flippers upward the skill shots - capture hole and spinner become almost impossible.

Thanks.

This is how I have mine aligned and I can hit all the shots.
Hope this helps.

Thanks. You have them aligned just slightly above the alignment holes. I will give that a try. Right now mine are centered on the alignment hole.

My understanding is that you put like a toothpick in the hole and that is the alignment height. Basically along the bottom edge of the flipper bat. Also, make sure the EOS switch gap is exactly 1/8 inch when the flipper is up. It makes a huge difference if that is not the gap.

If I use a toothpick for alignment, it feels like the flippers are set too high. If I center the flipper on the alignment hole the play feels right, but it is hard to pin a ball against the return rail. The flipper mechanics have a 1/4 inch core coil stop - later William's games had shorter cores - which allowed for the flipper shaft to insert further into the coil. Would a later coil stop work? I think the only issue might be screw alignment on the flipper bracket.

Gorgar is supposed to be difficult to trap on - it's a shallower flipper than many of the early 80s era. If you want to be able to cradle easier - replace the coil stop with a shallower stop from any of the major pinball part retailers.

As noted above - correct use of the holes is to put a pin/toothpick in the hole, hold the flipper to it (the plastic, not the rubber) and tighten. This is exactly as the user above has their flippers set.

Doesn't that give it a bit of ball bounce on it's way to the flipper? At least it seems that way on mine.

Your guides are likely worn down. Cliffy makes replacements that will give you a smooth transition like new.

I got Todd Tuckey getting my Gorgar ready, very excited to get my game in the house. Will have it soon, he’s making a video of the game. I’ll post when he send me the link. Great guy, really liked dealing with him!

I just read through all 17 pages and still no CPR playfield...

I'm looking to sell my Gorgar. Any advice on pricing is appreciated. Basically it's all working, but PF and BG are pretty bad. Cabinet is ok. On the PF, a previous owner put down full mylar on top of a dirty PF, and a lot of paint peeled off during removal. I'd say consider it a working player's game that looks pretty bad.

I have PPS Repro BG and CPR plastics, but figure I'd relatively try to recapture the price of those if the buyer wanted them. Otherwise they're not taking up much space, so I can hold on to them.

Yeah...I'm using them already. I think my playfield is a bit worn. I can't get them to hold in the right spot. Right flipper isn't bad, but the left one gets some hop.

Are your flipper mechs tight or can you move the flippers from the top of the playfield? You may have worn bushings. Another thing you can try is loosening the screws, putting some pressure on the guides so they are positioned better, and tightening the screws while you have hand pressure on them. If your screw holes are wallowed it you can do the toothpick trick. Make sure you put the toothpick on the worn side, probably the bottom.

Sounds like about $500 without the new backglass and plastics. To bad the new playfields are not out yet.

Hard to say what the market will support, but i suspect it will sell fairly quickly if listed at $500. Probably leaving money on the table, but descriptions aren’t as good as photos so it’s hard to say for sure and if truly as bad as you are saying, then $500 might be fair. I paid almost double that for one in decent shape... but not a great one. “Pretty bad” means different things to different people. I want to replace my PF and BG as soon as they have a CPR playfield out... but that doesn’t mean it’s bad, just not as perfect as I’d like.

Post some pics maybe?

So couldn't we find someone from CPR, here in pinside, and ask them nicely on some insight regarding Gorgar playfields?
