Video

I love this. How compatible is the firmware across games? Is writing something for a different game like mapping switch to sound files only, or more challenging?

Super helpful - thanks!

Great video and explanation. I love the bonus logic. Ted Zale was a master.

Great video on a game I'm also fixing. Mine has a bonus counting issue too. How did you set the machine up for testing the bonus unit for manual activation shown at 16:48. After setting up a few bonuses do you clip any switches closed then activate the lever? And if you don't mind answering, what glue did you use for securing the inserts?

Very well explained! Thanks so much! On top of the valuable lesson, I now know what that unlabeled mystery Jones plug purpose is! LOL (Score Motor power)

How do you turn the machine on, from inside

My ball is going through any wire area and it does not score.all other areas score.what do you think the problem might be.

I have a sure shot like yours.when I get a bonus ball it clunks before the ball gets down,so I don't get a free play.what do you do to correct this.

I like the idea of adding fresh, quality sounds to these old games. There is pinsound but this isn't compatible with the older games.

excellent, clear troublrshooting explanation

wonderful 👌

excellent video

Thanks for sharing! Would you go through troubleshooting from the start to finish for common problems, such as gi lights on but no game-ready?

TROLEX REPAIRS, why do some games don't save the highscore data to the CMOS chips when replacing the linear power supplies with a switching power supply it won't save the highscore data to the CMOS chips when using a switching power supply, not sure why.

One of if not the most boring pinball machine ever made.

What does the Arduino kit boards do to the pinball game? also what does the JUMPERS do to the pinball game? each jumper should do something I'm guessing to the address buss

Great technique thx for this vid!

Would you do something diff now with the Bally or Stern games of the pre 6803 era?

TROXEL, what is the purpose of the INDEX coil, and why do the pinball designers call it an Index, because what is it indexing?

How do "memory coils" drop off targets work? Because the ROM chips game code would have to store in NV RAM the drop targets coils state up or down state for player#1 and player#2. I think it stores the drop targets coils states in NV RAM or static RAM

Can you make a video lesson talking about the dual collect bonus unit how it's working well the theory behind it because it's a very interesting unit that I don't think most other em pinball games would have. Explaining the theory of operations would be nice but also another question I have I think a lot of the games were meant to be played with 110 volts of from the wall outlet and if the wall outlet is at 120 and higher at 125 cuz a lot of times it depends on the load the the flippers are going to be stronger and batting the ball so you're practically cheating the game and and the the game is not meant for that it's it was meant for $110 it says it on the schematic and as well as on the back plate of the pinball machine it should say 110 vac not 120vac something to check out look into the em games to see if that's true or not and get back to me in the comments thanks. If the em games were meant for $110 the insulation on the power transformer and the game is going to break down the insulation of the wire that's around the transformers going to break down faster as well as the coils The flipper coils and all the coils are going to be the lifespan is going to be less it's probably going to be 10 or 20% less because it's being worn out

Incredibly valuable technique. Thanks for sharing.

I had the SS version of Sinbad once upon a time. My godfather and I love playing around with electronics when I was growing up, and it evolved into repairing pinball machines! Sinbad was the one I miss the most due to it's deceptive simplicity, lol

TROXEL REPAIR, what are common EM timing issues? when EM games has timing issues how can you tell when an EM game has timing issues

One of the best EM diagnostic videos I've seen. Thank you for sharing.

I’m looking for this game

Thanks for the video & review! I just stumbled across it when doing some research

Sorry Gotlieb Airport is the game..

Cant get anything? When pluged in 120v to on/off switch then 1 1/2 volts?? How much juice should it have?

Nice analytical diagnostics. And good camera work too - it's not easy filming in those tight spaces with enough light. Previous owner obviously wanted to throw you a curve ball with the dog in the 's' position (and you can see the mark on the fork that it really belongs in the 'l' position). I passed up the opportunity to buy a 9/10 Sure Shot for a bargain price a few years ago and still regret it - I think it's the only wedge head that has a bonus feature.

Been watching a couple videos this morning on based on DickHamill's project. Thanks for documenting this.... I plan to have a go at tackling this for my Meteor & Trident (can I call it a Mermaid edition??) but your video was helpful.

Good info thanks.

Salut, moi c Philippe

Great explanation of what needs to be done!

Is this one for sale?

60's EM games used AC voltages for the relays, solenoids, coils and in the 70's they switched to DC. I'm not sure why when using AC voltages that the solenoids and coils are less strength and weaker compared to using DC voltage the solenoids and coils are stronger. For some reason which doesn't make sense is that 1 amp of AC current is weaker compared to 1 amp of DC current, any reasons why? this is why pinball games use DC voltages instead of AC voltages because designers are saying that AC voltages AC current is weak, not sure why.

Thanks for the make the video. Can you make one on how the lamp matrix and switch matrix circuits work in 70's and 80's pinball games because they use Diodes to reduce wiring harness but don't know how the row and columns works using a strobe signal with diodes.

What do you use to prevent arcing sparks from the voltage current across the contacts?
