Title: Which PCB version do I have?
Post by: naujoks on February 01, 2019, 06:38:55 am
I'm currently trying to sort out my newly bought cabinet with an original DK board inside.
Or so I thought, because when I start playing, after the first girder board is followed by pie factory, followed by springs, followed by rivets.
Also, on the high score list you can enter more than three letters.

It has Nintendo 1981 printed on the PCB.

Does anyone know what's the deal with this board? Ideally I'd like the original order of levels. The DIP switches don't seem to influence the order of levels.

Sounds like you need different rom chips.

Ahhhhh!
So different versions (unofficial ones?) are making the round?
Who could re-program the EPROMS for me?

That's the Japan version. Can you post a picture of your PCB?

Yes, here they are.
As you can see, someone soldered a JAMMA adapter to it.
I'm trying to get it to work in the cabinet (it's currently working fine withe 60 in 1 board), but there is some distortion to the picture (see video below) and the sound is almost inaudible.

Other than knowing that its a Japan set, hard to know which set it is without an eprom programmer to dump one of the chips and run it through romident.

Probably your best bet for replacing the erpoms: http://www.mikesarcade.com/cgi-bin/store.pl?sku=DKROMS

You're going to spend as much or more on an eprom programmer that will do the 2516's and 2532's and a UV eraser; and probably spend as much shipping both ways to someone who charges to reprogram them.

Although if it was my board, I'd want to keep those original eproms, with reprogrammed code, so maybe you can send them off to Mike for reprogramming.  And FYI, that masking tape over the erasure windows is completely unnecessary.

Also, is it an original nintendo cab?  If so, get rid of that jamma connector and clean up the pcb connector pads.  Seems like too much risk for shorting something with that thing dangling like it is.

Yes, it's an original cabinet.

Before I can go about and clean up the original PCB I would need to get the original board running, but the video and sound issues need to be sorted first.
It's difficult to find someone online who can help, even more so from a distance.

Do you have the original wiring in the cab, i.e. the individual connectors that plug into the board?  The soldering on the edge connector and that jamma fingerboard look questionable at best.  It could be the cause of the problems.

I didn't realize you were also the poster in the hardware thread.  To be honest, you will probably get better help on KLOV.  More hardware guys on that forum, and lots of nintendo and DK hardware gurus.

And just to be clear, that japanese code is not unofficial.  It's the japanese rom set, and I think with only 1981 Nintendo, is probably the ladder cheat code, but somebody may know better about japan pcb and code variants.

The common features among the Japan ROM sets are the fixed board order (barrel < pie < spring < rivet), the ladder trick, the title screen saying "(C) NINTENDO 1981", and being able to input up to 12 characters on the high score table.
