DiscoVision PR-7820

[MIPS]

After about two months of work and planning this thing landed on a workbench late last night. I'm gonna take a hit on this but I'm declaring it the first laser videodisc player to reach mass production, beating the VH-8000 almost exclusively by its internal use for quality control.

I'm working on pictures right now but immediately I'm running into three major issues. While it does turn on and suck a spinning disc under the fixed laser:

-The laser interlock is sticking. There is grease or a perished rubber bumper somewhere beneath the laser assembly that prevents the disc from automatically opening the path for the laser
-It's struggling to focus/find a sync signal off the disc. I can hear the focus servo run a few times before the player gives up. I can see some of the optics are fogged but cannot tell if this is front or rear coated mirrors which complicates cleaning them without scratching them
-There is an o-ring on the spindle lock that has perished. When a disc was loaded and clamped it immediately proceeded to glue itself to the disc hub.
