would this be a good arcade cab? Twin Cobra Project

Awesome, glad you picked this up. Toaplan games are always great and are in demand PCBs. Your monitor should have adjustment pots and might need a recap.

Awesome thanks for letting me know! I think I remember the NES version back in the day!

Here is something interesting, the monitor only comes on if this cherry switched is pushed in, it doesnt stay pressed so  have to tape it down. Seems weird should i just permanently wire it in? It already has a rocker switch on the bottom for power so not sure why it is like this.

The volume pot works so the sound is good now. Here is a picture of the switch.

[roflmao]

I'm guessing that switch once was located by the back panel so if some kid somehow opened up the back they wouldn't be able to shock the bejeezus out of themselves.

yes that is a "kill" switch, so that the machine would power down when the back was removed for maintinace  the "flyback switch on those old monitors can carry alot of juice! congrats on your first arcade cab! i have a ms pacman, and a ninja gaiden

ahh that makes complete sense, I didn't think of that because the switch is facing inside, it must have broken off and the previous owner put it on wrong. Cool! The PCB is really dirty so I am hoping that a good reconditioning of the board will fix the small graphic glitches on certain sprites. I may try to use a pencil head and press on some EPROMS while it is running to narrow it down later when I have time to work on this. But really excited, I am going to add in some new paint, probably mask off the side art.

I have built arcade joysticks before for consoles out of HAPP parts, so I am very familiar with upgrading those parts. Looks like the joystick panel needs some cleanup. And it needs a new Marque (however you spell that).

The music on this game ROCKS! Love this!

thats interesting because I looked at a SFII cab a while back  that was missing the back panel and it had the same button you had to hold in for it to work. But yea that totally makes sense.

YOU HAVE CHOSEN WISELY.

[ProfessorProfessorson]

Yeah Duo R, the stuff can be finicky at times if it wasn't taken care of. I had a Silkworm pcb with graphics issues, and I was never able to narrow down the problem, and a Martial Champion board which I looked at closely and found a damaged trace.

edit:man I should never post right after I just woke up.....at any rate, post fixed so it doesn't read like Regal wrote it.

[Duo_R]

I am a little scared of taking stuff out the of the monitor, I guess all the "high voltage" signs and knowing there is alot of power stored in there is what makes me a little nervous.

the thing to watch for on the back of the monitor is a big red wire, one end has a suction cup on it, attached to the monitor tube, the other end plugs into a large capacitor known as a "flyback switch" there are safe ways of decharging these, to make them prefectly safe to work on, but as a note just in general that red wire and capacitor are what you DO NOT want to touch.

See if you can pull the plunger out. It should click into place. That's how you override it for maintainance mode.

I remember those....Good Times. Welding screwdrivers to the monitor frame, roasting wires, etc. Those were the days

You have a ms pacman? Can you post pix of all the game boards for me, Please

(I can find pix of the first two on-line, but not the rest.)

ahh yes  lol, i use wire, alligator clips and a nice long flathead screwdriver, the only boards im familier with is the main board and the daughter board? which other ms pacman board are you referring to?

[TheOldMan]

which other ms pacman board are you referring to?

I knew after I posted that would be the question.
The mazes you play. If I can get a picture of all 4 of them, I can add them to Pyramind Plunder
