Can anyone tell me on 6A on the video board where this trace goes. I scratched the end of it it was solid masked and just looked like it ended at the 74ls04 chip I removed. Checked the schematics and can't find anything hooking to the chip all other traces on schematics had continuity. If anyone...

Thanks for the reply just bought a working motherboard from China so I will now have this as a donor board.

So does anyone have or know where I can just buy some of those parts.

Darksoft superbios Do you still have the superbios cart for sale?

It is worth fixing. It is not rare the 4 board stack were mainly used in the cocktail style cabinets as the original DK cocktail is smaller inside than the cocktail tables of a dk junior or popeye,thus it needed a smaller more compact board to fit the space.

third one down is the one you want http://www.spininc.net/PartsNewMenuSubCategory.aspx?sm=Parts&webCat=Monitor&webSubCat=Flyback

you can test it with using the individual cables in the popeye cabinet but if plan on hooking it up with the edge connector then you do need a rainbow connector.They can be bought at arcadeshop.com for $ 5.00

Looks like I was right after all. We'll see once you replace the ram.

all you have to do is replace the daughtercard with a z80A and then add the 3 bipolar proms and the eproms back.

If you can read the high score and the credit with fruit at the bottom but not the maze then check the 2125(93415) at position 2A and 2B also check for a bad 74ls158(quad 2 input multiplexer) at 3A.

I would start at the ram at location 4X. Even though your board plays pacman it could still have a failing ram that this diagnostic chip is finding.

That's what happens when you get free stuff.

I'll be there too. DogP has great arcade parties.

White screen is 90% of the time a power supply issue. I have had a rainbow connector where the pins had become loose and that was the problem. Also can we see some wiring diagram pictures to see if it is wired correctly?

Download the pinout wiring diagram and use a multimeter set to dcv and black to ground and red to pin of voltage you are measuring. But I think you have the rare game Donkey Kong Matrix :) LOL. http://www.mikesarcade.com/cgi-bin/spies.cgi?action=url&type=pinout&page=TRS.html

Your compact flash card is not large enough you need a 4 gig card. I had to use a 8 gig card for blitz 99 gold edition because the uncompressed hunk size was just over 6gb.
