Step #1 is get the key for the coin door. Here is the inside of the coin door.
|well hello in there|
|this is the coin acceptance mechanism|
|can you see that little metal lever, basically in the center of the photo?|
|oooo so rugged!|
OK, so now it's time to open up the playfield. See the opening in the top picture? See that latch at the top of the opening? That's the key to getting inside. As best I can tell, this is pretty damn universal for about 50 years worth of pinball. Pull that latch to the side and the front bar-rail comes off, and then you can slide the glass off. This is all summarized in this youtube video. That is a Simpsons Pinball Party. There are 40 years separating these pins and it is the same action.
BE CAREFUL. That glass is expensive, so place it somewhere where you won't bump it, preferably the end down on a carpet. (feel free to Windex at this point, I guess)
Remove the balls. This game only has one, so EASY. Pull the plunger out, and lift the playfield up.
At the back there are rails for the playfield to slide on.
|It's almost poetic. Almost.|
But hold on a sec, this meter goes to 999,999. I think that says quite a lot about the confidence in manufacturing. I'm not actually sure what other heavy-usage games from the era are reading, but to design a game that you expect to break half-a-million plays in a commercial setting? That shows some confidence in engineering.
At $0.25/play, 100,00 plays is only $2500, so it seems reasonable, but to think some of these might have pushed a half million plays ($12,500) by the mid-80s? That's impressive, even factoring in the maintennance.
Just to the left of this we have the awesomely simple tilt mechanism.
What I was surprised by though is that upper-left pinball. That thing is RUSTY, 37 years young, and if it rolls up it finishes a circuit and tilts. I'm unsure as to why they'd need that. If the machine was tilted up at the front, wouldn't the dangling tilt mechanism cover that scenario as well? But well, there it is.
Having the machine up also gives quick access to the playfield light bulbs:
One final feature from the inside:
