And here is a few pics of the board in action in my PP2 irish cabinet.

Hi there. I have recently made a small ARII replacement board for my PP2 arcade game. I will hereby share this board for everyone if you want to make a few for yourself. The schematics is a copy of the original one and requires the use of TDA2002's. I desoldered the original ones from the old...

Sorry for bumping this one. But does anyone know if you can get flat brown T-moding for Nintendo cabaret's?

Here ya go.

And here's before and after pics of the tube after pincushion adjustment.

Success! But forget about 5k. I believe the perfect pot value is 33Ω. I tested with several values starting with 3k, but very soon realised that the pot value had to be way lower. Here's a video of my chassis. https://www.youtube.com/watch?v=XSULrZlqsDM

Hi there! I also did a tube swap on a K4600 chassis today. I had an old Coke TV lying around. To make a long story short: it was a huge success, but I also have a slight pincushion issue. I'm using the Coke-TV's yoke. Is it anything we can do about this issue? Here's the yoke resistances: Old...

Put me down for an Asteroids CP please.

Post pictures (from at least two different angles) of the chassis itself (that's the big electronic circuit board under that tube).

It's through SCART. A european standard. See here on how to connect your SCART TV to a JAMMA board.

The issue is solved. After rechecking the ROMs I found a faulty 2716 at 7D on the video board. It's now working flawlessly! I got the hint from here: http://www.brasington.org/arcade/tech/dk/ It works! https://www.youtube.com/watch?v=27uSeG9soQQ

Yes, it kind of looks like the problems on this page: http://www.brasington.org/arcade/tech/dk/ (at the bottom of the page) I will have to recheck my ROMs when I get back home.

Hi! I've bought myself another DK board. This one was converted to Hero in the castle of doom. It DID work with that mod (after some minor repairs), but I wanted this DK back to it's original state. I've been burning new EPROMS and inserted a new Z80 and now the board is back to DK! However...

You are doing a great job! I will take notes of this for my own restoration. PS! So this is your idea of a clean up or MINOR restoration (as your thread title says)? :-)

Nice! I recently purchased an original Popeye PCB. Popeye is as far as I can remember the very first arcade game I ever played. I'm planning on building a dedicated Popeye cab. As I already have built a Nintendo DK cab (with ArcadeSD), I think the Nintendo cabaret is great idea for my next...
