Howdy,
I decided to purchased my very first arcade machine. I waited a long time looking around. I finally pulled the trigger on an almost mint condition Defender arcade. Spent $450, so quite a chunk of change, but it seems like a good deal compared to what I saw on eBay. It has a few issues, but I was hoping someone could point me in the right direction. Links to tutorials, videos, etc. would be very helpful. I'm going to start fiddling with it tomorrow.
The first issue is that the coin mechanism doesn't register coins when they're inserted. My arcade has three slots, the left is 25 cents, the middle is 1 dollar coins, and the right is 25 cents. Is there a tutorial on repairing and testing coin mechanisms?
The second issue is the joystick, it's fairly loose and doesn't go up very easily. This I'm pretty sure I can fix myself, and at the very least, just get a new one. No big deal there.
The last issue is the controller/dash overlay. The previous owner's friend melted it with cigarettes, then glued plastic on it. I was wondering if anyone has a new, old stock Defender overlay for sale? Once I replace that, fix the joystick, and get the coin mechanism working, it'll look brand new.
Attached are some pictures. It's a really fun hearing it turn on.

Kinda cool owning my very own arcade.
