would this be a good arcade cab? Twin Cobra Project

[Duo_R]

Ok i worked on the cab then moved the cabinet across the room, the weird part is now the right side of the monitor has a blueish tint to it. Sort of like i took a magnet to the right side. Strange, think i might need a new monitor? Seems hard to change out.

You probably just need to degauss it. My cabs and my PVM monitor have degauss buttons but you can make or buy a degaussing coil.
I found this page on how you can make a degaussing coil http://mirrors.arcadecontrols.com/OscarControls/degauss/index.shtml.

thats not uncommon with the old stuff either, slight movements can cause adjustments to go out of wake, and or also jarring can sometime cause symptoms of dried out caps to rear their head. i would say at best the monitor needs recapped,of course a new monitor is the best route if you have access to a replacement, depending on how much burn in etc is on the one you have now.

I am going to dishwash this PCB soon and recondition the board. The Jamma harness are all individually connected, would it be a good time to make a one piece jamma connector? So it is easier to plug / unplug games? Anyone know a good source for those?

I found a Sky Shark PCB last week. I believe that is by the makers of Twin Cobra? Is that worth checking out? I am thinking of building a Supergun.

Sky Shark is pretty cool. It's a little older but is still a lot of fun to play. Definitely worth checking out if you like stuff like twin cobra and 1942

Just to reinforce what Punkic already said: HELL YES, DUO R, SKY SHARK IS WORTH CHECKING OUT!

OK, that was just to get your attention. Now, in a more civilized tone:

If you are curious about old-skool shoot-em-ups, Sky Shark will definitely be worth your time. Even if you don't love it, it will help you fine-tune your preferences (which helps us make better recommendations, so it's a win-win).

ok....project Twin Cobra was put on hold for a while. But it is officially back in action. this poor cabinet took some abuse. I think the plexiglass on the control panel had cigarette burns? ewwwwwww

well no worries, I got new plexi from ebay on teh way, i'm swapping the controls. It had Wico joysticks which people LOVE but these ones were toast (robber grommet was shot). So just good for parts now. I got some HAPP parts that I will swap out. Taking off the panels and repainting. The unit is slightly crooked, I might put some feet on teh left side (like those small furniture screw wedges) and see if that works.

I got an original bezel for Sky Shark as part of a bundle - throwing it in there because I am going to swap in Sky Shark next. Need a new marquee and thinking about finding a LED light to replace the flourescent one with. We will see.

So in full gear...just took me a while. I will have 3 verticle shooters for this cab: Twin Cobra, Image Fight and Sky Shark.

I am going to next adjust the monitor and see if I can get the colors right, possibly recap the board. 

It's too bad I didn't take a photo of this when I first got it. It was in pretty sad shape.

JEALOUS!

New marquee - I actually just had a local print shop print the graphic for me, and they didn't even charge me...so that was free!




I replaced the control hardware. It had WICO sticks and buttons but all were in bad shape. Replaced with HAPP and cherry switches. Also swapped in Competition joysticks, and replaced the "bats" with balltops custom made by Tornado Terry. This was to match the look of the original WICO sticks.





Also replaced the back door, was made of particle board and was in really bad shape (chipped, warped, etc). New back door is made of MDF, and fits perfect. I added in the vent like the old door. Also added a lock to keep the kids out. I was thinking about painting it but doesn't really matter since it is in the back. Might be more trouble than it is worth.

Also I patched a bunch of holes, one of the previous owners just drilled holes all over....lol




redoing the electrical - it wasn't bad but you can tell they changed games as quick as possible (converted from Centipede to Jamma).

Ok so redid the wiring, the AC switch is now located at the top of the cabinet not on the bottom rear (what was Atari thinking on their cabinets).

I hooked up a arcade power supply. Now I measured voltage and I got the 5V almost exactly where it should be (after adjusting). The 12v however was like 10v and -5V line was about -4.4V. Is that acceptable? I know these are usually for speakers, but is that ok? Should I give it a whirl since I am only testing voltage and haven't hooked up the arcade board yet.
