Ron, you are absolutely correct on the 12 volt Hi and Low being amperage. The 2N3055 is a pass transistor that can deliver more current than possible with just the 7812 regulator.

Thank you atschimer

Exidy made a few very good games for the time,Star fire was amazing when it first came out,and also games like crossbow, venture,so im a bg fan..thank you as always guys for filming for us x

That's the first time I've seen an Exidy game fully intact. I recognize some of the individual parts, but never knew what they went to. Looks like quite an interesting setup, and a fairly impressive sound board for the time too!

[@raymondroot7457]

@@LyonsArcade someone thought that there might be a corrupt audio file causing a reset loop Not necessarily what I would have thought but it does kinda fit

[@chadhartsees]

Played this many hours on the ColecoVision ... but I'm sure these were all warehoused or converted to something else by the time I was old enough to be in an arcade. Never ever saw one!

[@DjResR]

Lo is low amperage and Hi is high amperage, usually a transistor regulator is used to provide high current because UA7812UC has 1,5A max current, in this case the 7812 is used as a reference to drive the transistor. The capacitors are there to provide noise reduction. Edit: Sounds like some audio file is corrupted and causes the attraction sound loop to crash and reset constantly._

[@robertsaltzman2481]

I like your videos so much... is it a compliment to say I even watch the commercials without skipping (unless there 5 min crazy ads) the only channel I do that with, does it matter?

[@LyonsArcade]

Thank you for watching Robert! We get paid a little bit by the commercials, so in general we make a slight bit more if they're not skipped, but you can skip them if you want, thank you for watching!

[@indydriver80]

It makes some good Halloween type sounds.

[@LyonsArcade]

Yes it does!

[@gregm1457]

Lo is a lead off the 7812/7912 high precision regulated output, but limited to 1.5a or so max. Hi is coming off the transistor follower which offers much greater power capacity (up to 10amps or so but I doubt the board can go that high), but the regulation is slightly softer. HI would be good for things light general illumination, Lo for circuits needing tighter regulation. That board should have some fuses...

[@goddessesstartrekonlinefle3061]

Looking forward to seeing what the game plays like. I used to play a game called Mouse Trap on my Atari (I think by RedRat software, if I recall correctly). I doubt its the same game, but I love the look of the cabinet and the sounds of the game play, so will look forward to your next upload. Thanks Ron!

[@texaricanapiaries4374]

Droopy and Drippy made appearances…. Memory serving

[@jasonhale4639]

a 2n3055 is a high current pass or power transistor made for passing current around the 7812 while still allowing the 7812 to regulate the voltage at 12 volts but allowing up to 15 amps of current to pass around the regulator through the pass transistor.

[@PlumGurly]

Yeah, I think in Tom & Jerry, there was a dog named Spike, I think. While I see a snake in a machine as possible, I'd think that cockroaches and rodent "evidence" is more common. On capacitors, if you have to, you can wire multiples in parallel to increase the capacitance. Or, if you have only twice the capacitance, you can wire them in series.

[@Vamptonius]

Definitely Spike. He had a pup too that kept getting into trouble that Tom got the blame for, if I remember.

[@gorillaau]

@@Vamptonius I think the pup was called Tike. It's been a while though.

[@weekendwarriorweldingdiypr4604]

I think when you finish a series, the videos should come out daily, like you did over xmas.

[@LyonsArcade]

Unfortunately the videos step on each other if you do that.... you get about 60% as many views if you put videos up daily, then if you put them up every two or three days... because it takes people awhile to watch your latest video. If another new video is out by the time they get ready to watch one, they miss one of them and the views are less.

[@weekendwarriorweldingdiypr4604]

@@LyonsArcade makes sense to me... thanks for responding!! Keep up the great work. Been watching religiously since covid started. Almost 3 years.

Yeah. Always bugs me that tubes only shows videos in reverse order so you get series backwards. And now they've removed the option to list Oldest First so you're stuck with Latest or Most Popular.

I remember that game but never played it. Kinda looks like an Atari cabinet, but not. Different design!

[@charlesclark2917]

The instructions make it sound trippy, but I looked it up on MAME and it's similar to Pac-Man game. A year later, Loco-Motion came out, and boy did I drop a lot of quarters on that game. All I remember about Exidy was their also-ran Z80 computer.

[@SpearM3064]

That would be the Exidy Sorceror. It wasn't really Exidy's idea; it was the brainchild of a guy named Paul Terrell who owned a chain of 58 computer stores and happened to be friends with Kaufmann and Howell Ivy (VP of Engineering) of Exidy. Only produced for about two years.

I never understood how Namco didn't sue them for this one. The video game market was very competitive. The leg out of the socket thing is like nails on a chalkboard with me.

I wonder if it would be a reasonable idea to try plugging a different known good monitor into that game just to be sure that the no video issue is not a failed monitor?

JOE CLASSIC< Do you figure out what that +12vdc HIGH means and what the +12vdc LOW Means? The High and Low must mean something, if you have a current CLAMP you can measure the current of the HIGH and LOW to see if the currents are different or the same. I wonder if the service manual will tell in the tech notes what the high 12vdc and low 12vdc means because I'm curious

[@Vamptonius]

Most comments say amps.

@@Vamptonius thanks for the info

[@SpaceCop]

That control panel is an abomination! Sticks on the right? I'll never understand that.. Do you have a favourite right-hand-stick game you've come across, Ron?

[@LyonsArcade]

Let me see if I can help you understand it. In 1981 when this game was made, there had been very few games with a joystick, most of them before that had buttons. Some games had a joystick in the middle. So they sometimes decided to put the joystick on the right, because people in general are right handed. What is so hard to understand about that? Why would they assume you want to use a joystick with your left hand, if you're right handed? In this game, pressing the buttons you could do with your elbow, you don't need any dexterity to press a button every once in awhile. You need more dexterity on the joystick, it's used more. Centipede has the trackball on the right, BURN IT DOWN WHAT WERE THEY THINKING

[@SpaceCop]

@@LyonsArcade Thanks for breaking it down for me, a simpleton. Trackball on the right I get, as to me, you often need that precision of hand directional control in the angle of roll/attack on speed rolling ["golden tee"], and finger strength/dexterity for precision movement [missile command]. I remember ambidextrous games (stick in the middle) , I just can't recall that many right handers that weren't modded to be that way. I wasn't shitting on mousetrap, just looking for some insight from someone who's probably had thousands of cabinets pass through his hands. So basically, being a pioneer is tough and with 40 years of hindsight, innovative choices can look questionable. Makes sense! Please don't lump me into your cantankerous hater category! :D big fan, watch every video, love to learn along side you.

[@AvengerII]

OP, You're wrong about right-handed joysticks. That was STANDARD for years! It was only AFTER Nintendo started selling the Famicom/NES that left-handed directional pads and lefty joysticks became standard. I had 2 of the old videogame systems -- the Odyssey 2 and Atari 2600. Guess what? The joystick controllers on BOTH those systems (which were late 1970s vintage) were right-handed with the single button on the upper left side. Most of the early third-party joystick controllers (Wico's among them) were also right-handed. The only controllers I have at present that are right-handed are flight stick controllers for simulators and arcade/action games like Ace Combat. Throttle is always left hand control, the main stick is right-handed. That's because they emulate real-life aircraft controls which are standardized around right-hand controls because 90% of the population is right-handed! The arcades and fighting games in particular went in the opposite direction (left-handed) because it raised the challenge for gamers and made more money for arcades in the long run (or at least the limited time arcades had in the West before home consoles and PCs became powerful enough to make arcades seem pointless to most people)! Left-handed is still the preferred format for fighting games because A) it's tradition and B) many fighting game fans are masochists!!! LOL Doesn't matter to me, honestly. Joystick controls are one of the things were I'm ambidextrous. I learned to play right-handed first (despite being a Lefty for most things) and then was forced to switch to left-handed control because of the Nintendo NES system pads!

[@AvengerII]

@@LyonsArcade Pac-Man is one of the few classics where they deliberately left it up to the player to decide which hand to use to control the character. There were no buttons to use other than 1P or 2P buttons and those have no function other than to start the game! I think Donkey Kong might have been one of the first arcade games that forced you to use a left-handed joystick with a pushbutton controlled by the right hand. It was also a four-direction control lever, a point that Billy Mitchell dismissed when he cheated for his DK high scores!

[@SpaceCop]

@@AvengerII at the very least I'm happy to say I started a civil discussion on the internet, I may have been a little too evocative with my "abomination" description, but I fully admit.. it's my bias talking. Thank you for the history lesson, people!
