Bally's Cybernaut Pinball Was So Obsolete They Ran Out Of Chips! 

The first blue LED was created in 1972 by Herb Maruska. The first blue diode was presented in 1992. The first blue LEDs were developed in Japan in the early 1990s by professors Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura. Their work enabled a new generation of bright, energy-efficient white lamps, as well as color LED screens. The breakthrough came in 1986 when Akasaki and Amano created a high-quality GaN crystal. In 1990, Nakamura also successfully produced a high-quality GaN crystal. In 1994, Nakamura used a double heterojunction InGaN/AlGaN to produce a device with a quantum efficiency of 2.7%. This opened the door for efficient blue LEDs to be easily produced.

Yup, as others here have said, the light strip behind the tube on Xenon were originally just regular white bulbs. But what I came here to say was that one of the things that I've always enjoyed about your videos is the highly detailed notes that Joe always leaves for you after he's inspected a machine. 🤣

Actually, the original lightbar on the tube were made up of small lamps, the kind with only legs. They probably have a fancy name I don't know about. The blue LED's came later. I remember first seeing blue LED's in an electronics catalog in 1990 and they cost something like $50 a piece.

I'm really not surprised that they swapped the CPU to the MC6802 - the original MC6800 reference design included an (expensive) hermetic metal clock oscillator unit (MC6871?) that generated the two clock phases that the MCU needed - the MC6802 included the clock circuits and just needed a single external xtal and also had 128 bytes of built-in scratchpad RAM in page 0. Since most MC6800 designs included both clock generator and a RAM chip to provide the zero page RAM switching to the MC6802 would reduce your BOM cost with zero effect on software compatibility. So many people changed over to the MC6802 that the original MC6800 quickly became a rather high cost and hard to obtain legacy part. In fact, this was one of the very first jobs I was given as an EE - replacing a MC6800/MC6871/MC6810 combination on a control board with a MC6802 + xtal.

You should leave a note for Joe, it’s Fixed 😂

I so like your KISS (Keep it simple stupid) way of troubleshooting. Great video Ronnie!

I truely enjoy your repair videos. Thanks for spreading knowledge and history.

I've been sick for a few days now. Nothing serious only a cold with some sore throat and I feel weak and a bit dizzy. I have a broken neglected old Gottlieb Circus that I've been working on recently to make it work and presentable again, but this damn cold is preventing me from continuing to work on it. I've got bored laying in bed and I checked on youtube to see if there's any new video from my favourite pinrepair guy to make me feel a bit better and now here it is. Thank you, Ron. Keep up the good work, I love your videos.

Hey Ron!! Love the Pole Position attract sound!!

I really like the little Pinball History segments - please keep them going.

Looks like a fun one! Hope you bring back A.R.T. Sundays, i really enjoy them.

I owned one some years ago, fully working, absolutely loved it! Mine had a different coindoor and front though.

Super cool game. His mind is going to be blown when you are done.

That’s one dust encrusted, display entombed, 1985 genre, nasty @$$, la kooka-raucha, southern style! Hey! Who remembers the … it’s Shake-n-Bake and I helped! Commercial? 😂

The space shuttle on the backglass of this pinball machine is named "Defender." That's a reference to the classic side-scrolling shooter videogame, "Defender," ALSO made by Bally Midway when they were still the same company. Midway, Williams, Bally...! It gets confusing because of the corporate reshuffling! Anyway, I like their pinball machines better than their videogames.

Lovely looking backglass. Look forward to seeing the machine firing on all cylinders.

i adore you guys! i'm so glad i found your channel!

I’ve not encountered this machine at all. It seems like it’s gonna be a pretty fun game….Regarding early 80s pinballs, they obviously were in a down period. …but then the 70s were such a hard act to follow. Consistency is almost impossible to achieve consistently. Pinball has risen from the ashes a few times over its history. …just wait for The Addams Family, and so many great games in the 90s. Thanks for the vids. Always fun.

I can attest, the two shirts are great items! Thanks for going through the process on this one.

Nice that was a quick repair😎👍

shoot! You got me again! First with the squalk and talk. Now with the cheap squeak. I was sure it couldn't be real. 😂

Nice rare machine Ron. I wonder if the emergence of new games like Pac-Man, Galaga, Ms Pac-Man, etc along with home games like Nintendo NES, etc caused a lot of the decline in the pinball scene of the 80's.

Once again... Joe is spot on with his analysis. He really is good at pointing out the problem. 😁

Looking forward to Part 2 of this table.

Wow! What a difference in the sound!

Never seen or played this one before,exciting x

Love it. Thanks guys!

Awesome game. The trick to playing the game while holding the camera is to put the camera in your mouth. Keep up the great videos.

I'm sending my English teacher to your shop to fix your "broke" speech, She has her own multi-meters and soldering iron. 🤣. Another great video and s sweet pin.

Great video Ronnie, Can not wait to see the finished video. Looks great and fun game. Yes, Xenon does have a led strip of lights next to the tube. See you on the next video, Ronnie

OK I WANT THAT PIN ! Cybernaught is super badass! No Speech but SUPER COOL!

@4:20... I would buy a "We unbroke it" T-shirt..... just say'in

That thing sounds just like my stomach after a spicey meal LOL!

I’ve never heard of this title. Dig the art though, really 80s sci fi.

Cheap Squeak was designed as an inexpensive alternative to Squawk and Talk with speech. You can thank Bally engineers Lance Chantry and Bob Kohan for the curtsy board names.

Very cool game, never heard it or heard of it before. 1984 was one of those years where video was king, even if the crash had affected the industry to the extent that there were fewer new games (video *or* pin).

I remember the Hardbody game. I used to play that one regularly. I never saw Spy Hunter as a pinball though.

stencils are cooler but need to be done perfectly for better details, and silk screening looks better with less time and effort. Bad silk screening looks light years better than bad stencil work every day.

The Motorola 7802 is pin compatible to 6800. My Firepower uses it. It also has ram in the 6802.

Great video ron

Cool game. Is there a Babes of the backglass video? Should be!

Yea, those lamp sockets and light boards! The context of this comment is that those same components and lamps were used in auto dashboards in that same time period for years AND THEY SUCKED! 'Nuff said!

I will never get tired of "Its broke!" -Joe

I saw the Gottlieb coil on the pop bumper and thought to myself, Did I work on this? I know it wasn't actually me because I've never replaced a pop bumper coil in a Cybernaut, but my philosiphy is the same. If it is a similar coil that will work just fine, I don't care which coil it actually is. Just make sure the diodes are correct (if there are any) and it will work just fine. I've done it many times.

6802 were in TONS of industrial boards, cash registers and some traffic control.

Is the back backglass reminding you of the Star Wars Leah pose?

What a beautiful table… but it’s Ducken Fusty!

the bally 1971 Four Million B.C. already had a ramp made like this one

The pinball market crashed in the early 80s (aswell as the arcade game market for a while) due to the advent of home systems like the Atari 2800, it really didn't bound back until the early 90s with machines like Adams Family and Creature from the Black lagoon with digital audio and dot matrix displays

Dual Precision Mono-stable Multi-vibrator, that's a mouth full.

I doubt the LED strip you mentioned was blue since blue LEDs weren't developed until 1988 and didn't really hit the market until 1992.

Cool game. I have never seen this one before.

Poor Shane. Dual Dracula’s.

Blue leds were invented in 1989 and it wasn't till 1992 before they came up with bright blue leds.

Very cool🎉

Ron, I have been watching and enjoying all of you videos. I feel like you are teasing me with a beautiful (hopefully its a EM) but ignored pinball machine. That is normally to the right of a pinball machine that is being repaired. It has sailboats (I don't even like sailboats) on the side and I am hoping one day that fine machine will get some Ron love with a set of repair videos. (Rant time) Your fluke meter is too clean!! please get it dirty and grimy its hurting my eyes, it looks like a prop instead of a real meter LOL.

That's a coil eating roach...There's your problem...LOL!

… the sound setting probably resets to 0 when capacitor discharges

The lights on the Xenon tubes were white.

I think the industry having collapsed was likely tied in with the home computer and console scene. There was the video game market crash, and later, the home computer price wars.

I remember playing this one when I was in my teens. The artwork had to be great because the table play was very average.

The bug's broke.

NEAT game. I don't remember it, but hey...I don't remember a lot of things any more. Question: Starting to see a LOT of pinball popping for sale (for LOTS of $$$) that LOOK to be Stern or Bally or Gotlieb, and have the names, but they might be 1 player games, or 2 player games only. These are the same titles that you're working on that are 4 player. The seller is always saying "RARE 1 Player" or "RARE 2 Player" game, and super inflated prices. Many comments on them saying "These are not rare, they were 'home version' games that sold for a lot less, and were very cheaply made. Any info? Would love some machines, but alas, SWMBO says NO. :(

Yodelayheehoo

Linear are nice , except for the price of rebuild kit 75$ for 2 flipper, come on now people!!

MULTI BALL !!!! That's a cool term It just sounds cool Xenon is really awesome I always wished someone would have made a pinball machine based on the movie EVENT HORIZON If you have never seen it, the cast is great and the acting is perfect and the science behind it is real and the visuals are cool There are so many scenes that could be a part of a pinball machine The Gravity Drive The LifeBoat The suits The explosive charges If you watch the movie and then go back and watch it a second time and think about the parts of the ship that could be a part in a game Just an awesome movie And to have a bunch of spinning rings with thr lights and you hit tue right drop targets and ramps and get the rings to lock and the gateway to open. It would be so cool to have the spinning rings around the center and have the lights all come on. And they could have a display in tue backglasd with thr scene and the effect of the gateway and the sounds So many cool sounds The lightning storm in space Check out this movie and tell me what you think about this movie being used to make a pinball machine

Could that strange creature remind you of the creature in the movie Alien.

Can you not use cols out of telephone relays to replace the burned out relays 600R coils.

Any chance there was a video on that old wood-rail pinball next to this?

Hi guys I have a question for you after watching some of your vids I decided to check the end of throw switches on my Williams firepower machine and to my surprise there is none is this normal or has someone removed them for some reason machine plays ok .looking forward to your reply thanks so much .ps I'm in Australia if that makes a difference. Thanks Stewart

What is an MPU exactly? I know what CPUs are but not MPUs, or the differences between the 6800, 6802 & 6803.

What about a MC6809E CPU

I never really got why TAF was such a huge hit… I liked it but in the same way that I liked all pinball machines. I see it’s cited as being because of its great game play but I guess I just don’t see it; great game, but not THE game for me. Regards

Rare

It’s broke. 🤣🤣🤣

i don't think joe has ever been wrong. it's always broke.

bed bug

that is a cockroach, nice game though!

"It's Broke" lol so thats why its in the workshop...

L-Roach-O
