Why not bump a thread. I finally got DK2 and wanted to share it with those who may not know about it. Also since I last updated this post, I've done the following:
-Replaced the non-working coin mech with a working one.
-Replaced the P2 joystick with an original one.
-Replaced the missing coin tray.
-Recapped all the boards and power supply
-Tried to fix a video glitch unsuccessfully. After talking with other owners it seems to be a board problem
-Added a new lock to the coin door.
-Removed the Z80 CPU and put a socketed version in it's place, for DKII kit
-As of yesterday installed the Donkey Kong 2/High Score save kit.
For anyone unfamiliar with Donkey Kong 2, it's a sequel to the first Donkey Kong with many all new levels. You can either get a chip upgrade for your Dedicated Donkey Kong machine or buy a multi game board that also has it. I, of course, bought the chip and added it to my board. Here's info on the game with screen shots.

Now not only does my machine have to seperate games on it, but Donkey Kong now remembers your high scores and initials when you turn it off. I don't know why I'm writing this for people unfamiliar with it, since most who hang out in this forum probably already know most of it... but just in case someone accidently clicks on the link who may not...
So the kit cost $79, and it's pretty awesome. The challenge to adding this kit to my machine was that I have an early board set, where the CPU wasn't socketed to the board. So I had to remove the original chip, and replace it with a socket and brand new CPU. Here is the process I had to go through.
Here's where the z80 chip is located.
Here's a closer view.
Here is the empty space where the CPU used to be.
It's nearly impossible to remove a chip with this many legs and reuse it. I cut the legs and saved a lot of time.
Here is the socket that is key to adding the multi kit. If you're z80 isn't socketed you won't be able to add the kit.
Here is the socket now attached to the board.
Here is the kit.
Here it is on the PCB set, ready to go back into the machine.
Anyway I figured this may be useful to 1 or 2 people if they ever stumble across this thread. And also I just figured I'd also update what I've done, to the machine since then. The machine works great still, and now there's quite a bit more replay value. The one downside to this DK2 mod, is tha it took away the ladder cheat, which comes in handy on the Girder stage. Most Donkey Kong machines don't allow you to do this cheat anyway, except the really early machines where the ROMS weren't updated.
