I’ve had some arcade game movement in the past couple of months so I thought was time for another update.  I still haven’t made much ground in any of my restoration, although I was able to (poorly) paint the Donkey Kong cabinet I picked up in Louisville.  I picked up a new paint gun so I’m going to have to take another shot at it.

I also patched and (mostly) prepped my Donkey Kong Jr cabinet for painting.  I want to get it ready to paint before doing the cabinet mentioned above so I can knock them both out in the same day.  I decided both will be turned into Red Donkey Kongs and I will either install original DK boards or go with a 60-in-1 multicade setup.

As far as purchases go, I picked up a couple of cabinets in Ohio.  The first was a non-working Crown’s Golf game I picked up in Cincinatti for $20.  I messed with it a little but no luck getting it going yet.  I figured it was cheap enough so I might as well pick it up.  Maybe I could use the monitor or power supply.

Also, I found a deal on a Golden Tee 98 in Columbus.  The listing said the game worked, was upgraded to Golden Tee 2k courses, had a “new” monitor, and a new power supply, but the image was upside down.  Easy enough, I thought.  Either the monitor was installed upside down (it could happen) or some wires were switched.  But, when I got up there, I saw that the image was actually split with part of it being upside down.  It appears as though the frequency is wrong for monitor.  But it’s a standard res monitor and a standard res game, so that’s not it.  Everything is wired properly.  For now, I’m stumped.

I had a 25″ TV taking up space that I wasn’t using, so I purchased an RGB to NTSC adapter and inserted it into the cabinet.  Unfortunately, as expected, quite a bit of signal is lost in the conversion process so it’s not the best solution.

However, just a few days ago, I saw an ad for some games available near Cincinatti.  Available were a Ms Pac-Man, a Nintendo Playchoice 10 with 7 games, and a Teenag Mutant Ninja Turtles.  If I had the right vehicle, I would have returned with all 3.  Unfortunately I only had room for one, so I opted for the Teenage Mutant Ninja Turtles.  The cabinet is exactly the same as My Golden Tee and it was working, minus the control panel.  So, I bought it primarily for the 25″ monitor.

After returning home, installing the monitor in my Golden Tee, and firing it up, I found out that this particular monitor requires and isolation transformer.  Oops.  I immediately blow a fuse.  Fortunately I’m prepared for this and have more fuses handy.  After installing an isolaiton transformer I had laying around… I blow another fuse.  Not good.

I go online and seek help from the fine people at KLOV.com.  They gave me some hints of what might have gone wrong with too much power.  It looked like a lot of work ahead.  I removed the monitor chassis and found my ground trace on the edge of the board was completely fried.  That was an easy enough fix by running a wire to bypass the burned edge.  Someone told me to check the bridge, that 2 of the diodes would probably be shorted.  Bingo.  I had to google to determine what the bridge was, but I found it and 2 dead diodes.  After a trip to Radio, I mean, The Shack and a couple of assorted packs of diodes later (wouldn’t you know they didn’t have the exact ones I needed in their packages) I replaced the 2 diodes and hoped for the best.

In the off chance that my isolation transformer was bad, I lugged the 25″ monitor back downstairs to try in the TMNT again, since I knew it was working fine before.  Fortunately, it fired up and worked just fine.  After reinstalling it in my Golden Tee and replacing the sync wire, I finally got to play the game it was meant to be played.

I still have a couple of small issues with the monitor but nothing major as of this point.  There’s a small spot at the top of the screen where the image is shfted but it’s not that noticeable yet.  The monitor will need a cap kit anyway, just to freshen it up a bit, so hopefully that will take care of that issue.

And finally, my Red Donkey Kong has taken its spot in the game room.  I still need to do some touch up work to it, but it’s cozy for now.

So that’s my update.  I now have 4 (mostly) working games sitting in a garage about 3 hours from here, 2 Donkey Kong cabinets in my game room (1 having a Donkey Kong Jr board installed), a Golden Tee in my upstairs office, 3 Nintendo cabinets, a Centipede, a Crown’s Golf, and a TMNT cabinet in the garage.  I need to start making room soon.
