I just purchased a non-working Donkey Kong on craigslist and need some assistance from the wise ones. It has the two board Nintendo of America setup. On the main board the cpu was missing. I've purchased one from Mike's Arcade, do I just plug the new cpu in and go? Also there were two ceramic capacitor disks that were loose on one side. All I can read on them is 103Z. They are in locations c140 and c154 on the board. Can I just use any 50v 103Z or does it have to be marked 10 or 22 like the others?
Thanks for any help you might be able to give.

likely they are just bypass caps or power smoothing caps.
either way, the voltage won't make much difference. they would be 0.01 uf 50 volts (according to the code) but you could use a larger voltage if that's all you had.
ceramic caps don't really go bad, so if you can solder them back solid again, they'll be good to go.
as far as your CPU goes... hard to tell... it's always a crap shoot if you inherit someone else's machine. you never know what they've done to it or why it's CPU is missing.
it's possible someone just stole it to fix another machine, in which case... it should be good to go with a new one. otherwise... :dunno

This has me interested. Keep us informed how it goes.

Kudos to you Kevin, most people's first post is about some ill advised arcade playin' furniture they plan on building. Your jumping straight in to fixing original hardware, good luck and let us know how it goes!

What's the model number of the PCBs? I'm assuming TKG4 but I couldn't find C140 or C154 in the TKG4 CPU or video schematics. Its sort of like "Where's Waldo?".
