Quoted from Whridlsoncestood:

Send me a message next time your in the area. I’m always willing to open up if I’m around.

Thanks! We were just down for a couple of days: 500 mile road trip to pick up a smartball table in East Haven, and to get our fix we stopped in at Barcade in New Haven. Our big mistake was staying at the Red Lion in Cromwell. What a disaster. Maybe my favourite CT moment: Ate my first hot buttered lobster roll ever at Sam the Clam - now that was something! I might come back just for that.

I work in Branford. Right next to east haven. Bummer we didn’t cross paths.

My Sterns are loaded up with these obsolete .05 M 100v capacitors. What is a good substitute? What is a good substitute that does not cost an arm and a leg?

And where do you buy them?

I learned something today that I thought I would share. I imagine some of you know this already but if you are using on altek board in a Stern 200 game you must change the clock setting jumpers over to the left side or else the machine does not play right. everything is slow. That was new to me and fixed my problem perfectly!

Ive switched over to using the weebly boards...

#808 10 months ago

I ran into that trouble shooting an original MPU-200 with Split Second... Was switching the Altek in from a strikes n spares to test some functionality.

Also made the move to Weebly. Great product, better price, and great support. I had some weird sound issues with his MPU that he helped me shoot through

tl;dr - I originally ordered it for a Big Game, but ended up testing it in F2K... there was a trace that wasn't populated that is needed for voice on MPU-200 games, and he offered me full shipping costs to return the board for a new one or to help me do the trace. I said board work was no issue and he returned with detailed pictures/instructions anyone could have followed. Highly recommended, solid dude.

Hey guys. I actually also have switched over to Weebly boards but I like to have on altek on hand so that I can troubleshoot it in any old Bally or Stern but I like the Weebly board action as well.

Is that trace only populated if you tell him it’s for a game with speech? Or was that something in the last that has changed?

One of my Stern 200s was bought from a retailer and shipped in. The shop owner said he had to play test it before before I could buy. He finally gave a thumb's up and I had it shipped across the country.

I set up and plugged in. That pin was dog slow. I'm thinking about what kind of mess I had got myself into. The flippers were weak. The pops could barely push the ball. All of the feature lights were flickering. I had forgot about those Alltek jumper pins. I spent quite a while trouble shooting the problem and then remembered about moving those jumpers. Sure enough, the retailer and his mechanics overlooked the jumpers. When I repositioned them the pin sprung to life.

That was a close call. The retailer knowingly sent something substandard out the door for primo price. It if had been something more serious. I would have never gotten my money back.

For me, there are even more reasons to use Weebly boards. For Bally rom hacks and rom testing, it is a great tool as well.

A big benefit these days is the ability to use custom roms as well.

#814 10 months ago

If you guys haven't seen Weebly now has an all in one board similar to Altek and cheaper. A friend just informed me yesterday, check it out!

I just purchased and installed the https://pinside.com/pinball/market/shops/1055-nvramweeblycom/01281-new-universal-bally-stern-replacement-mpu- in my Stars.

Another reason I went with nvram.weebly is because of the use of through-hole components allowing me to easly repair later if needed. I can also set for free-play and use it to test with in many other machines.

Couldn't be happier, works great!

I'm going to be needing some boards in near future.

The Weebly products look interesting and pricing is more friendly. And I know barakandi is a pinsider.

Alltek boards have the lifetime guarantee. Does that lifetime guarantee make the Alltek products worth the extra money?

What kind of warranty do the Weebly products have?

Don't know about guarantee but weebly has been incredibly helpful with support via PM or email any time I have used his products. Faster response than any other pinball product or company I have dealt with.

I've NEVER had anything made by Andrew fail. Having said that, I have known him to stand behind his products. I would PM him or email him directly regarding warranty questions.

I understand that, I just don't want something inferred if it ins't true.

#823 10 months ago
Quoted from Whridlsoncestood:

From talking to him, it was an older revision MPU board. I guess someone else had the same issue and he had already fixed it in his latest revisions. When he designed the board, he looked at the schematic and didn't see any use for the trace, so it was left off the original design. Since I was getting it for a Big Game that didn't have speech, he sent one of the older boards.

I didn't save the Email off hand and it was a few months ago, so I don't remember which trace it is - but if anyone ever runs into the issue and needs, I can pull my board and look at my trace.

Quoted from TheLaw:

They offer multiple game selection as well, but they also use surface mount components.

Quoted from cottonm4:

In my communication with him, barakandi said he stands behind his products pretty much for life, as long as they haven't been hacked up or poorly resoldered.

#825 10 months ago
Quoted from Whridlsoncestood:

Is that trace only populated if you tell him it’s for a game with speech? Or was that something in the last that has changed?

I fixed this missing trace around June 2018, all boards past version eight or so will have this track and will work with Stern Speech. If you are unsure look by the J4 plug. If there is a pin silk screened labeled LAMP INT then it is ready for Stern games with speech. If the silk screen print LAMP INT is not by J4 then a jumper will need to be made for Stern Speech games.

When I originally did the board I saw "LAMP INTERRUPT" on the mpu200 schematic and though "huh, no reason the lamp board interrupts the MPU so I can leave this out". That was a mistake and the lamp interrupt is what triggers the speech card to read the lamp address/data to play speech. Only effected the few Stern games with speech.

#826 10 months ago

I had a minor issue with an Alltek board and it was replaced immediately with the latest revision. I've purchased a ton of his boards for MPU, SDU, and lamp driver and only had that one minor issue that was immediately resolved. Weebly gs Ben my go-to for rectifier boards as it saves me a few bucks with the roll-your-own option. You can't go wrong with either company as far as I'm concerned.

#827 10 months ago

Does anybody have classic stern lockdown hardware looking for a home? My Stars has the lockdown bar with the round pegs but no locking hardware. PM me with your monetary demands!

Great to know. I think I’m around 16 classic sterns right now. Gotta be rocking 8-10 of these boards at this point. Keep 47 games going at The Sanctum too I’ve started keeping some of these on hand for quick swap outs

Do the weebly boards support free play for sterns?

#830 10 months ago

Nice! They do have free play. I may have to get one.

#831 10 months ago
Quoted from SR230CC:

All the MPU100 (and Bally)games have free play which you can turn on/off by a dip switch setting.

The MPU200 games have an alternate ROM that is always free play.

I am having a problem with the right sling on my lightning pinball. It works in test but does not work during game play. Sometimes it may ghost work and activate when not struck by the ball. I am not a repair person and any information will be conveyed to my pinball repairman, so forgive me if I cant answer any questions as to what has been tried already but we believe that it may be a faulty cap.

Sounds like sling switch is gapped too close. Possibly touching. If a vibration happens(flipper etc) it causes the switch to open momentarily and fire again. Check that first. Check the switch edges in switch test.

The thin metal bars just inside the slingshot rubbber should be close to the rubber but not touching. It sounds like they are touching, or they are so close that when the cabinet is touched lightly it makes the rubber touch the metal bar and fires the slingshot coil. Bend the metal bars a little bit away from the rubber. This should solve the problem.

Quoted from Whridlsoncestood:

Chances are good. Right now time to work on new projects is limited. I am hand assembling everything still and I can hardly keep up with what I am currently doing.

For the SB100 I finished the schematic about a year ago and did the board layout over 3-6 months back. It is a rough layout that needs tweaking for sure. Also pretty sure there is going to be some surprises and revisions needed. There was so many schematic errors in the original SB100 drawings I am not sure I have found them all.

For those taking notes... here at the errors on the SB100 schematic identified so far (some of these discovered by others and I thank them).

- Q1 emitter (top of C18) is connected to +5V VDD (schematic does not show any 5V connection)
- U6 Q output is pin 3, not pin 13 (the flip flop in the sound effect section)
- Pin 25 on the J1 connector (reset line) is not connected to anything (rev C-1)
- U19 (LM556) power pin is not connected to VCC, it's connected to +5V VDD (from the 78L05)
- R11 power is connected to +5V VDD
-inconsistent 5v labeling
-4013 U9A P6 "channel one set" not drawn anywhere. Probably gnd (yes?)
-U6 is connected to +VDD, not +VCC
-R3 and R7 are connected to +VDD

Rough board layout rendering attached...

The stargazer was on kijiji (kinda like craigslist) owner got it with their house when they bought it a year ago.
Was taking offers over 3k. I paid 4200cad (about 3k usd) for it which might be a little high with the playfeild and backglass really bad, coin door and legs repainted poorly but boards were clean and it was working 100%.
