Thanks, Del! :)

Well explained!

OK! OK! OK! After every sentence OK

I'll have to try that sometime.

I sounded different? :)

John's Arcade Game Reviews & Tech yeah when you are working on the game, not when you are doing the viewer mail

That's not a bad thought! :) Part #4?!!? LOL.

Don't know if that needs to be filmed. LOL!

You should mark it as you dont know if you sell it in the future

You could save little bits of footage like that for an end of year wrap-up. Not big enough for a video, but mashed up in a collection

+Gary Sweetland we need the transformer for the monitor isolated voltage

Ahhh..... Now I understand.

Hey, Chuck! I thought about this but just didn't like the idea of that PS still running.

I look forward to your NVRAM install video! in Part #4?

There is an argument for not putting the fuse on the "ground" wire to the coin door bulbs, as they will be sharing the same ground at the SMPS. So, if the +5V supply to one of the bulbs shorted to the chassis ground, then it still wouldn't pop the fuse. So yeah, usually best to just add separate fuses on each of the +5V supplies to the bulbs, as you've done in the vid. Or, just add one fuse to the +5V supply, then split that to each of the bulbs. I prefer the idea of just using the SMPS too. It's true that there wouldn't be any current drawn from the linear PSU (well, maybe a tiny amount), but it's nice to not have to worry about something else on there randomly shorting out.

Yes. I have a new CPO for it. We can do it.

john Dingo-Fox off to the hanger making money. you have to be pretty well off to have a new machine not making coin and sitting in a basement

Yogi bear with a beer can in his hands!

+Andreas Lindholm I know this now. I'm always thinking out loud in these vids. I'm glad I talked myself out of that. :)

Yes do not fuse on ground. This in case of a fault on the way to the load. Assuming the chassis earth ground is somehow bonded to the psu ground such a fault would be just as bad as no fuse.

I always get a ghostly voice just whisper dont do it when im toying with an idea. Arcade Gods looking over you dude lol.

+dave -weldore- newton blue scotch locks?

+dave -weldore- newton oh I know what you're taking about. Those come with all the AS kits for that purpose.

the ones you connected to the monitor supply for the mains that are hanging down i may be wrong but im sure they are 12v connectors

dave -weldore- newton all the AS kits use those for the AC.

probably fine on 120v ..just never seen them used over here in the uk on a mains supply...i had you best interests at heart :)

+Gary Sweetland No. :(

Bummer....!!

+Mac Donalds I've had nothing but problems with the two 28" Polo 2s I have for my Time Crisis. The flybacks in particular seem to be really flaky. The 20" Polo in my JAMMA cab is on its way out too... I guess given their age they've done OK, but you look at the monitors in John's machines which are over a decade older than the Polos and they're clearly not as robust.

+Marc Bollinger really? Ok.

Did I say bulletproof in this?! :) 6100 has been good so far. :D

bulletproofing means you might survive a bullet, not that it won't hurt if someone shoots one at you.

Optical Trace Ah! A Llamasoftie! I actually chat with the ol' Yak reguarly on the #llamasoft channel on Blitzed IRC! Feel free to join me (JFD62780), and mention John's Arcade so I know who I just replied to! ;)

+unknown 12.

You can tell who skates and who doesn't...

I am gonna keep an eye on it. There might be a part 4 with the NVRAM upgrade.

Riz2336 I use the nvram on my Joust.

I read the sheet wrong. It looked like a "-" sign in front of the voltage. It was a "~". I need glasses.

Haha, but then... I'd think someone with enough techie would already know not to read that ~ as a -, simply because of the technicality. Hmm. Well anyway, that's why you can put an annotation over the top of the video everywhere you say that. Maybe something like, ''Negative AC? No such thing! What was I thinking?!" Right?

+Jay agreed

Rebuild your original power supply. And fix your hacked harness.

Rename the Video, How not to fix your Robotron power supply.

I always rebuild the linear PS. I like my games as original as possible.

>He is worst then Old operators back in the day. That's absurd. Most "old operators back in the day" wouldn't have even left that machine as a Robotron. In '86 it would have been converted to e.g., Double Dragon. In '89 it would have been converted to e.g., Final Fight. In '91 it would have been converted to e.g., Street Fighter II, and so on. The original sideart was often hastily rattle-canned over with no prep work, wiring hacks were often of the "twist-n-tape" variety, lock bars were often installed over the coin doors, and control panels were often "Swiss-cheesed" to accommodate a different set of controls. John may not be an absolute purist, but he's a lot closer to one that most operators were. Of all the things I've seen people obsess over in this hobby, obsessing over having the original power supply is perhaps the most ridiculous. Replacing a linear power supply with a switch-mode power supply doesn't affect the gameplaying experience at all, nor does it change the external appearance of the cabinet. If 10 Robotrons were lined up, all powered on, some with linear power supplies and others with switch-mode power supplies, you wouldn't be able to tell which was which.
