Quoted from jrpinball:There are thin metal prop rods in the top edges of the cabinet sides which can be pulled out to support the glass assembly if you choose to leave it on the game when servicing it. Bally made several models with this type of arrangement.
That's interesting, so it's held up by the cabinet and not the head like my Jolly Ride? Do you know if the glass needs to be all the up with the Bally version?
One annoying thing with the Playmatic version is that I couldn't use the device that holds up the glass due to my ceiling being too low. I had to keep taking the whole thing off when I wanted to work on it. Luckily I have a higher ceiling in the new section of the pinball room, so no longer an issue.
