Here's the power supply, the fan, located top left moves back and forth a little but doesn't go into a full spin unless I blow a little canned air on it:
My marquee has one lock on it, I'll check around for some small keys, maybe one of my work keys or a generic file cabinet key might work on it, otherwise I'll have to unscrew the whole thing and buy a new lock. The lock looks pretty generic.
And here's my one-slot Big Red.
Got a lot of cleaning to do on it. The front has chipped a little bit as you can somewhat see in the picture. It's not in its final spot yet since I'm still fiddling with it. I'm trying to get a tech from a local coin-op retailer to come out and replace the capacitors and I'm going to pick up a degaussing coil soon. I'm still salty that my "completely shopped out" cab is in need of so much work already.
