Hey Classic Stern fans, I'm about to start restoring my Quicksilver and I have a question regarding the coin door. What do people do? Powdercoat or paint? And what colour? What about the coin mechs? zinc plating or polishing? Thanks.

Paint it with Rustoleum hammered silver. There is a slight blue tint to it so you could experiment with silver over blue, but silver alone is acceptable.

I’ll have to check if that’s available in Australia. Not a brand I recall, but thanks.

It’s available from Bunnings. Rustoleum hammertone

#2207 61 days ago

Gotta have your hammered silver!!!

But as also heard it only works perfectly in over 80 degree temps, to really get the true effect.

#2208 61 days ago

Found some competition video on Lightning, first I've seen. Too bad the spinner is borked but worth a watch.

Lightning’s in all our competitions. Will be in 24 hour final battle circuit event and possibly pintastic circuit event 2020.

I really enjoy the rules/how it plays. Huge joe joos jr fan.

Make sure to sand/score the legs before applying or else the paint will have nothing to adhere to and will eventually flake off.

No. I wish. These inserts don’t age well. Mines very cratery. Greatwich John does backglasses.

#2213 60 days ago

Ok, not expecting many answers on this but here goes!

My Catacomb will 100% of the time award an extra 20000 points each time a drop target set completes. It shouldn't award anything except 1000 points per drop.

Putting an Alltek board in, the problem vanishes.

So, how on earth do I fix the Stern MPU board? Any idea which component might be responsible for the behaviour?

Thanks

I just looked up your MPU board picture you previously posted and notice you have RA28G ROMs meanwhile RA32 are the version in the wild and what I've twice recently seen.

We need you to get your ROMs dumped! They might be special with other differences!

FYI, Alltek is running Catacomb code matching the RA32 code.

#2215 60 days ago

Thanks - so it's basically early code?

I guess they decided it was too easy awarding 20000 for each set of drops.

My game is an early German version, with the letters, and I think the audits go back decades.

#2216 60 days ago
Quoted from cottonm4:

Dead Dragonfist:
I have been having some spirited sessions with Dragonfist for the last few days. This morning, the good times ended. During mid-ball, the pin just froze up. I can turn it off and then turn it back on and it is still frozen. It does not reset. It does nothing but light back up with the same play field lights frozen and a blank back box.
I have not started trouble shooting this yet. I thought I would plumb for ideas before I start looking around.
Is it something simple? I don't know yet.
Have I blown a fuse? I don't know.
Has a connector pin gone bad and folded up? I don't know.
Has something gone bad on a board? I don't know.
The pin is equipped with an Alltek MPU, a Bally SDU, and a Bally lamp board. It also has a new Weebly rectifier board.
As I said, it just quit cold. And is frozen.
Any thoughts on where to start looking are appreciated.
I have to leave and spend the day running errands.
This is it. I have GI and a few feature lights. Nothing more.
[quoted image]

Finally got to Dragonfist this morning.

It was a blown fuse on the rectifier baord. A 4amp fuse on F3. It is working fine now. But my big question is why did the fuse blow in the first place?

Is there something I need to be worrying about? Just what caused the fuse to blow? Or does this get filed in the "shit happens" file and I move on along like nothing happened?

Thanks all for offering suggestions.

#2217 60 days ago
Quoted from Shapeshifter:

Potentially yes. Looks like the German Stern ROM list for Catacomb may have started at version 25 - see page 3 of the below pdf.

It would be great if they could be dumped and the code preserved for the community.

Did the old fuse blow violently or was it just open circuit? Got a picture?
Do you have LED displays?

I agree as it changes the game totally scoring 20000 after completing a set of drops.

Wonder which version is most fun to play?

#2220 60 days ago
Quoted from Shapeshifter:

The question is whether there's other differences in your version.

#2221 60 days ago

I will study the ruleset in more detail, but I haven't noticed anything else.

#2222 60 days ago

I would say it blew violently. There is quite a gap between blown electrode?/wire.

I have the original Stern displays installed.

It looks like it was a new fuse that blew so it had already been recently replaced?
Suspect it will probably happen again till the cause is found.

#2224 59 days ago
Quoted from Quench:

It was a fuse that was supplied with the Weebly rectifier board.

I had played quite a few games over several weeks before it blew.

At least it did blow. So I will keep playing. I’ll start studying the prints and track the circuits and try to figure it out.

#2225 59 days ago
Quoted from Tsskinne:

I had a Nvram.weebly board in my dragonfist with similar behavior, wouldn't get past the second flash. Swapped in altek board and it was back up and running. I haven't bothered to take a look at the nvram board yet.
I do have weird behavior from my upper right drop target bank. If I knock down say just the lowest drop target, but don't clear that bank and then I drain. On the next ball even though the targets all reset if I hit just the top two the bank will act as if though it has been cleared and reset and award me the bonus X for that bank if it is lit. It could be any of the drops in that bank as well not specific to the lowest one, and it doesn't seem to do it all the time either. I have tried different versions of the code, different boards, my switches are well adjusted and I've replace the diodes on all of those switches as well...
I'm guessing I'm just left with connectors at this point but wanted to see if anyone else had a similar experience by chance.

Hmm that might be a software bug I've noticed something similar before on DF. It's probably not clearing the flags correctly. Does it ever happen in a multiplayer game and if so does it stay on the same *player*?

Good question. I’ll check it. I think it traveled from player to player but typically I play it alone so unsure.

If you cant to keep the game OEM...
Just order the tungsten contacts from pinball resource.

#2231 58 days ago

https://www.marcospecialties.com/pinball-parts/SW-10A-48

That's the cheapest that Marco has that will work I just use this type in all my games if I'm not just replacing the contacts. Sometimes I take the stack apart and put it into the original stack so I won't have issues with spacing but most of the time this one works out of the box.

You won't find an "original" replacement so if that's important to you, get the contact like vec-tor says.

Very nice stream man! Any chance you are ever going to reproduce those stern aprons like you did for the bally games? I have your Fathom and Centaur and they are just amazing! My Seawitch and Stargazer could use the same love.

#2237 57 days ago
Quoted from Tsskinne:

Any chance you are ever going to reproduce those stern aprons

I collected some decent demand for Stargazer, Quicksilver and Seawitch. Probably enough to justify making the metal tooling. Splitting up the volume to print the individual titles is one of the issues.
Stargazer has a light blue with white screen OR dark blue with yellow screen.
Quicksilver has black base with green screen OR dark green base with light green screen
I think seawitch only has light blue base with dark blue screen; not sure if there is a 2nd version.

The dilemma: Choose one variant for each game and go with it OR further dilute the volume and make some of each.
Known issues:
- Pinball Rescue already sells decals for the screen portion of the art, which I believe has kept the demand for a new reproduction part relatively low. Not as nice of quality, but presentable.
- Stern's aprons where made of a thicker gauge steel than bally, so the original steel is likely still in good shape compared to the flimsy Bally's

Not saying it won't happen, just showing all the considerations when thinking about making these.

#2238 57 days ago

well, crud, I went and messed up my Lectronamo somehow. Has a new Weebly CPU board in it too.

Had it actually playing a game, except the outhole coil wasn't working. The coil ohm'd out ok, voltage was good, and I could fire it by grounding the transistor tab. I didn't have any transistors to spare, so I pulled an unused one from Q1, and used it to replace Q4.

Well, something happened the game just didn't like!

I get into attract mode, but it doesn't reset the drop target banks during boot, I don't hear the relay clicking during boot, and even testing at the CPU board I don't have any stuck switches but they do show up during switch test. I did re-install Q1 with a fresh TIP102, but no change.

Displays work, controlled lamps are working, I have solenoid voltage.

Not terribly familiar with how the MPU-100 works, so not sure what I should be digging into next. From all I understand, if a PIA is dead, it shouldn't get into attract mode.

#2239 57 days ago

Just to confirm, it looks like I'm able to register switches on the upper header, but not on the lower header.

I can trigger all coils, and the flipper relay, by grounding their respective tabs on the solenoid driver board.

#2240 57 days ago
Quoted from cottonm4:

Stern made two styles of lockdown bar receiver assemblies. The early ones, like Dracula, may or may not have the ball and socket type of receiver. The later Sterns replaced the ball and socket with a slotted type of receiver.
If you have a slotted type of lockdown bar, you may be in luck.
Stern/Data East used the same style of lockdown bars as found on the classic Sterns form Ali and on. My DE Robocop lockdown bar will fit on all of my Sterns.
If you have the slotted style of lockdown bar this receiver should work OK.
https://www.marcospecialties.com/pinball-parts/500-6881-00
This is a DE lock bar that works with that receiver. I don't know if this is wide body or not. Pay attention.
https://www.marcospecialties.com/pinball-parts/500-5757-00
Pinball Life also has the slotted receiver.
https://www.pinballlife.com/stern-front-molding-lockdown-bar-receiver-assembly.html
If you do have the ball and socket type of lockdown bar and do not wish to change and if you really want a ball and socket receiver, your best way to source this part is put up WTB ads, or watch Ebay. Be caeful with Ebay; Lots of sellers will not know the difference.
Or in general, just get ready to beg.

Quoted from cottonm4:

I do not completely understand. Pinball Life sells DE lockdown bars. And they don't have any receivers to fit the DE bars they sell? I'm glad you scored yourself a Big Game--Orbitor 1 lockdown bar. And none of the receivers they had will fit?
On the left is my Nine Ball bar receiver. One the right in my Data East Robocop bar receiver. They are the same.
BTW, From Ali and on, Stern produced two lockdown bars. One bar is for the narrow body pins such as Seawitch, Quicksilver, etc. And there is the wide body lockdown bar for Big Game, Cheetah, Freefall, and I feel safe in saying Orbitor 1 will use the same lockdown bar.
Pinball Life is selling DE widebody lock bars and narrow body bars. I would think that one of the receivers Pinball Life sells would fit the DE bars that are selling. But who knows?

cottonm4 you were right sir! I finally received my Data East lockdown off a Pinsider parting out a WWE and it fit the Orbitor 1 bar perfectly. No idea why Terry thought they didn’t fit.

I can trigger all coils, and the flipper relay, by grounding their respective tabs on the solenoid driver board.

Measure the voltage at test point TP3 on the solenoid driver board. If you don't read 5 volts, you've lost voltage to the solenoid logic and predriver circuit on the solenoid driver board. Usually happens due to a bad connection on the 5 volt loop wire at connector J3 that runs from pin 13 to 25.
See the section from the solenoid driver board schematic below:

SDB_TP3 (resized).jpg

#2244 56 days ago

Might be onto something there. Crimps do look pretty poor, but unfortunately I'm completely out of hand-crimps right now, have to order more.

Goofing around with the connector I did get some momentary clicking of the relay and solenoids..... now my MPU LED just locks steady-on when I try to power it up. So going to dig deeper into that connector.

What an odd design.

#2245 55 days ago

I always hard jumper that Brn-Wht connector in order to make sure the board gets the +5 volts.

#2246 55 days ago
Quoted from HHaase:

What an odd design.

Bally probably designed the board in sections, or used manufacturer reference circuits and that was the easiest way to link it together. The jumper fix has been SOP for many years now though but I admit I'm lazy too and don't always implement it when I go through a game (depends on how bad the SDB is in it)

I’ve been on an early stern streak it seems. My first was Meteor awhile back which i still have. Next was a Trident. Then in the past 6 months I got a Cheetah (blue cab), Wild Fire, Stars and a Dracula. I need a lockdown bar for my Cheetah, would be great if anyone could help me out with that.
