I couldn't tell you the last time I've seen one work that well

Hey I will buy this if your willing to sell

Any idea I can get info on buyer 😏

Zach. I have the same machine. Can you help me with mine?

Hello, I could use some help with Mt model s if willing

Cool machine. Who is the PBR you mentioned twice for parts? Thanks

yes all the cool stuff from when we were kids are dieing from bad caps . the cool part is they were built well enough that they didnt need much else . rectifiers and reapplying heat sink compound goes a long ways

is it sold ?

Are the sound effects or sound test available on the S Chip? Like of I bought am S model eprom and put it in a special eprom sound effects mp3 player o have from Chuck E. Cheese they used for sound effects on a chip, would o be able to scroll through all of the various sounds on this eprom too? BTW are "Skeeball Too" eproms hard to find? I had this whole box and power supply from a CEC version of Skeeball too bit before o realized the sound was stored on eproms I trashed it! Aggh!

Pretty cool! Beats the old funky Williams test fixture . =)

Nice fix! I think I've seen this one other time before. Rare for sure. Thanks for posting!

Came across your video and wondered if you could give me some insight as I am having issues with my SkeeBall game. I have a SBC-1-B-SP31A board. When I plug it in the fan will start, but no lights, sound, display, or ball button will work. It was working fine before, but all of a sudden had this issue. I tried unplugging and re-plugging and reviewing to see if there was any loose wires. None that I could see. My game is all original incandescence bulbs. I did not take the metal box apart to see the entire PCB. Any thoughts on what to look for or idea what is causing this?

thanks for the information. I like your approach.

That’s a weird one

Zach I've seen a number of your videos re: skee ball machines. Are you able to reprogram the ROM on a classic skee ball? I have a model H that seems not to have the correct version of the firmware to support the 100 point holes but I understand that there is a version that does. That version is publicly available but beyond my ability to upload to my CPU (which is working great, just without this capability). Thanks for any assistance that you may be able to provide

can you please tell me the difference between the model S and the model H? Thank you

I have a pcb of this why are they so expsenve tho?

That’s actually quite something.. I’ve never seen those caps EVER fail and worked on hundreds of these

Woah, is this one with the version that Nintendo pirated?

this look fun (in 1980's)

Hello Zack I have question can this arcade screen connected with mister fpga ?

Generally the side of the fan that has blade guards is the output side; this one looks like it’s pointed up, which is the opposite as you described.

I was running a Rottendog MPU 327 on my Black Knight to. I found it had bugs in the program where the machine would crash during play and revert to Game Over mode. It also played havoc with the speech on the sound board. I had to get my orignal boards refurbished no it plays beautiful...

Williams sounds from the 80's were the absolute best!

Great video! Had my BPM for years and never knew this. My locks are missing. :)

Awesome - thanks for the info!

thank you. What a feature-filled machine!

This video deserves a comment . The sounds from this Game are nothing short of amazing . what an incredible layout .

Great video! Do you accept chassis for repair?

Zach we have had a 1991 Skee Ball machine for several years now. We have the dip switches set for free games and no tickets. It has worked great for the last several years but recently when power is turned on the 4 lights for free game, game over and winner illuminate but the ball count display and the scoring display do not light. Nothing happens when you hit the game start button. Any suggestions.

On the LED versions you need that extra "white" wire because, the chip is a UCN5833A Serial-Input Latch Driver. Lookup the datasheet for the chip. If you trace it out on your display that white wire goes to PIN 4 which is the "Strobe" pin, this has to be set high after the end of the clock signal for 100 nano-seconds. I learned this when I was building an Arduino based controller. It will control the mini-bulb version and also the LED version but without that white wire the decimal and the number glitch like you showed. I learned from your video using pin 6 on the 4-player display allows you to use the LED display, very cool. Hit me up would love to chat about these.

Zack-you are amazing. I've watched my machine deteriorate. Now it lights up but doesn't start, no scoring, no solenoid ball release. i put a button in to bypass the coin switch so that doesn't work anymore. I'm not an EE, just a real estae lawyer. keep the machine for my grandkids. they reach under to release the balls! there are buys on ebay looking for $850 to repair the board! Any suggestion? Machine is in boston area going to Cape cod in a month or so.

Nice find

Would love a drawing of your wiring harness you made up and what is the plug called that starts game and counts the 10 point scores

Great video! Didn't have the same issue but you showed the board which is what I needed to see. Seeing how clean your board was, do you repair? Do you have any working Model-S boards you would be willing to part with? Rehabbing a neglected Model S right now. Excellent overall and thank you!

Great video. Thanks for the detailed information on how to decipher the horseshoe unit.

Awesome Explanation

nice

Great videos!

Your sound test produces the sound of the Elvira lock. Interesting, Earthshaker is my all time favorite and I don't have it on mine. Which rom sound revision is it?

You didn’t show the cartridge, so I’m going to assume the video’s a lie

what kind of grease do you recommend to regrease the sequence motor. super lube ?

Interesting back glass. Ive seen a couple of designs but not that one

I actually own one! I worked fine when I got it, but it sat in climate controlled storage for a few years. The scoring is not working. I did try the units like you did in the video, they work, but the score still does not show. Any suggestions? Thanks for posting this video. Much appreciated!

ZACH GUTZMER, why does AC coils & solenoids make a buzzing sound, is it from the 60hz frequency on the AC line? why do they have less power when pulling and releasing?

Following. Are you restoring it for yourself or for sale later?

thank you for this video!

I bet that bottom corner lifts up
