A friend of mine picked up this little tabletop pinball toy manufactured by Marx Toys. I figure that it is probably from the late 70's to early 80's, just based on the 'Atari-Like' font they used on the front of the box. However, it is not affiliated with 'Atari' in any way from what I can tell.
He asked me to look at it as it wasn't working all that well considering it's age. So, I cracked it open on my home bench and discovered the simplicity of the toy. Basically, there is a metal ball bearing inside the table that is fired around like a real pinball machine. The bumpers on the surface have two contacts in them, one is a sprint to bounce the ball and the other contact is on the bottom under the spring. So, when the ball hits the contacts, it triggers an electromagnet inside that strikes a bell and also moves a mechanical points counter. Basically, that's all there is to it.
The flippers are moved manually with hand-grip levers that you squeeze. The ball launcher is also mechanical and works from the center of the table.
The ball and the contacts have become somewhat corroded over the years so the ball striking the contacts does not always trigger the electromagnet. I was going to pop the table open to clean up the contacts but found that the table is actually assembled in such a way that you would have to break it permanently to get it open. So, unfortunately, this is one old vintage device that is better off not being messed with.
So, I basically just cleaned it up and oiled a small lever connected to the magnet and bell. The bell is louder now but the contacts are still flaky. That's okay, it isn't the real deal and I doubt the owner is very concerned about that anyway. He just thought it was a neat toy from the days of his childhood.
It would make a better decoration on a shelf or hung on the wall I think than anything else.
