Just a quick post. Since I am in to arcade machines, and if you’ve read the previous posts on this blog you know.  Today we officially launched the youtube channel arcade impossible. It is going to be a youtube series where we look on ebay/craigslist/anywhere to find the arcade machines from the 80′s and 90′s, buy them, and try to build the best possible arcade, at home.

Follow along here:  http://www.youtube.com/arcadeimpossible

Donkey Kong Arcade Machine Restore

Posted: May 2nd, 2012 | Author: | Filed under: Tech | Tags: , , , , , , , , , , , , , , , , | 2 Comments »

Back in 2008 I was getting in to MAME arcade machines. I think I even have a few posts on this blog about the Dig Dug machine that I gutted and made into a MAME.
Seeing the film “The King of Kong – A fistfull of quarters” really solidified my want for a REAL Donkey Kong cabinet. One reason being that after I saw the movie I initially played on my MAME Dig Dug machine until I got to 21st place in the world back in 2008 at 184,000.   So I happen to come across the machine on craigslist. A buddy of mine found it on the Janesville, WI craigslist site and sent me the link. The guy was asking $300 for a fair quality Donkey Kong cabinet. I got him to let it go for $280. The only problem was the red color no longer output to the monitor properly.

So I got it home and powered it up, and took the geekiest picture I could think of.

 

Here are some pics showing the general state that the machine was in, bad t-molding, chips, cigarette burns, etc.

I got the machine out to my garage and got to work.  :)

Note the monitor chassis bolts.

And the blue-ness………Why Red??!?! That’s my favorite color.

The first order of business was installing the Cap kit.  A cap kit is where you desolder and resolder in new capacitors on the monitor board.  Over time the sweet goodness in the capacitors can dry out, leading to dull colors and even colors missing completely. ;)

I was really worried about stopping my heard and being unable to start it up again, so I read this site many times on the precautions and used speaker wire with a clip to ground out the NODE (cathode or anode..I’m blank right now).

Bingo, now that I’m not dead (thank you friends) here is the removed monitor board:

A shot of the 4-board version of my DK board.  This is the one where it says “Nintendo” on the main screen, not “Nintendo of America”.  So I was able to use the ladder hack and never have a barrel land on me as long as my hand was at the top of the ladder.  Unfortunately, twin galaxies does not recognize scores submitted using this board! So I need to find a 2-board version. TKG-03 is the current board.

So guess what? The cap-kit on the monitor did NOT fix my issue with the Red color not being displayed.  I found this site: http://www.brasington.org/arcade/tech/dk/ which shows screens of each chip being disabled, so you can locate your problem.  I had a bad 2J PROM chip, yaaaaay!  So what did I do? I ordered a new PROM set to replace the bad one on my 4-board version, and also ordered a 2-board version that is recognized for setting official scores.  So now I can sell my 4-board, because the 2-board is now in the cab and working great.  The 4-board is fixed too!

Look at that! I beat my previous record on an official 2-board dedicated Donkey Kong cabinet!

Now to fix up the machine.
Here’s what I ordered:
-New white t-molding all ’round
-New overlays and instructions
-New coin sticker
-New joystick repair parts
-New buttons (stupid smokers)
-New plexy with art for the control panel
-New Side-art
-Donkey Kong Blue paint bucket
-Replacement LED backlight for marquee

I started out by sanding the crap out of the machine until it was smooth, then bondo on all of the imperfections.  Most of the corners were pretty beat up so I had to use some shims and nail them in to make perfect corners.

Shot of the underside of the control panel.

Bondo…

All taped up and sanded.
I went with 3 coats of primer paint white, and 4 coats of Donkey Kong blue.  Turned out AMAZING.

Here’s after all 7 coats:

Sand blasting the coin door and repainting made all the difference.

 

I had a blast.

The back looks soo much better without the chew marks. lol

 

All in all, I had a blast on this project, and LOVE playing this machine.

I think it looks great in my (old dining room) Arcade.  :)

Thanks for checking this out! Let me know if you have any questions.

MAME – The build, the legend, and I finally documented some work!

Posted: September 5th, 2008 | Author: | Filed under: Uncategorized | Tags: , , , , , | No Comments »

Januaryish 2008 I picked up 2 arcade machine cabinets.  Vindicators and Dig Dug (both for $70ish total).  I happily gave the Vindicators machine to my friend Matt and began gutting the dig dug machine as soon as it was in my garage.  I remember Matt telling me to take pictures and document my work because it is really interesting to read about peoples’ builds online.  But no, my obsession with getting it done in less than a week made me forget about taking any fabrication/build pictures.

Not this time though!  I decided to redo my machine after moving to Illinois because my Dad has a bitchin’ wood shop.  I took pictures, time lapse videos, and I used Cherry for the control panel! Cherry switches…why not have Cherry wood to go along with it??

Here is an original Dig Dug cabinet picture for reference:

Here is what it looked like after my 5-day gut/mod fiasco:

Not too bad right? Wrong! Most of my favorite games use the 4-way joysticks.  This is a big problem if you have 8-way joysticks installed.  The new version has selectable restrictor plates that can limit the joysticks to 4-way and 8-way, that is going to significantly increase my Donkey Kong score.

I’m surprised how much interest an old arcade machine sparks, my entire family and a few friends have helped out so far.
Here is a pic of my brother cutting the Cherry directly out of the shelf! We couldn’t get it out any other way.

My Dad’s saw blades are kind of dull, we smoked out the house twice cutting the hard cherry.

Here is the wood all angled and ready for hole-drilling. The trackball fits perfect!

Cherry is a hardwood.  I’m really glad we have a drill press.

Here is a picture of the control panel with all of the controls mounted and ready to rock!
If you are curious, I am leaving the control panel woodgrain.  Why? Because according to my Dad, “It is a sin to paint Cherry”.  And I am not a sinner.

Just for reference, check out the old pine control panel that will never be used again.

The sweet wiring job I did on the new panel!

The 19″ LCD that I used to make fun of every time I went to Matt’s house.  Thanks again Matt!
I wont be making fun of it now.

Catfish? They speak like the french.  wee wee yuaa yuaaaa

Wow I have A.D.D.
The only things I have left to do on the arcade machine are:

-Setup fluorescent bulb behind marquee and mount switch on top-behind cabinet
-Mount motherboard and computer peripherals inside the cabinet (mimicking the original ROM board location)
-Paint the cabinet
-make surrounding trim below the control panel
-make trim for monitor (not cardboard this time!)

Here’s a time-lapse video of everyone working on the machine, it looks like I didn’t do much work, but I did 80% of the build so far.

I’ll append to this post when I have another update.

—APPENDED SECTION—

I finished the machine!
Here are the updated pictures.
I also worked for 6 hours or so on a DJ stand this Saturday.
ENJOY!
