DiscoVision PR-7820

[Ed in Tx]

I was thinking there is some sort of polymer or other material holding the mirror-coil to the magnet, but it's been 40 years since I dissected one.

Did you get it to play yet?

It's still doing the same thing. I have not attached a scope to it yet or any multimeter as all the major boards are underneath the spinning disc and service jigs are needed to break the wiring out. I want to be sure the disc won't spin off or scuff before I start hanging wires off it.

I've had no luck so far still trying to figure out a replacement piece of rubber.
Meanwhile I have scanned in the programming reference I received with the player for the Model Three upgrade. There appears to not be another copy available online digitally, just for the Model Two, so this should be helpful to a few people. Please note that while I removed the original staples and the pages were still tight, pages 89 to 101 are missing.

Edited: Actually, if anyone wants to look at ANY of the available service documentation I have on hand, I just uploaded it all to archive.org. It should come up in the texts section of you search "Discovision".
