OK!

Or visa versa.

I'll have to try it on my 1987 Pioneer after I move. It did have some (existing) clouding on that disc, so it may just be a lost cause.

Born and raised in Detroit, I run across these G.M. discs at flea markets all the time.

Also I wonder if a pre 1980 LD player like the OLD Pioneer with an HeNe laser instead of the semiconductor LED system would punch through? Those could play really bad discs better than the LED systems could. More power I guess?

The top-loading players are actually better with old discs than the later players. I keep a few around just for them.

Exactly! The top loaders like the Pioneer (no Magnavox they just had too many problems) did indeed handle poorer quality discs. I know they went to the laser diode due to cost, and for the most part they did their job. But those old top loading tanks, they really were well built!!

Ben mentioned some clouding on the disc he couldn't remove. What most likely happened was that the previous owner who attempted this didn't dry out the rubbing alcohol quickly enough, thus clouding out the disc. It's unfortunate, but I doubt that even a fully restored PR-7820 would be able to play it.

IMO a high end machine may be still able to play it, but we'll probably never know. BTW, what Turtle?

Search for "laserdisc turtle."

Some industrial discs used MCA coding for player control. Consumer players will not play MCA coded discs since they are made to comply with the LaserVision standard, which uses Philips coding. That said, it's possible that the dead side which wouldn't play may also not play on a machine that can work with MCA coding or a player that doesn't pay attention to any control codes at all, such as the Pioneer LD-660. The Pioneer player that was used to attempt playback threw a P5 error code, indicating that the player couldn't read any signal off of the disc. In the case of a dead side, this may be a sign of a defective pressing that was so bad that it wouldn't play at all. In the case of a good MCA coded disc, the same player would be able to lock onto the track, but would abort playback after about 5-10 seconds because it couldn't read a control code it could recognize when trying to read the TOC. An error code would be invoked, but it wouldn't be a P5 since the player could read a signal off of the disc but couldn't detect a recognizable control code.

The GM discs were designed for the PR-7820 player. Some older players will be able to play the disc, but without trick play functionality.

It has an it is dead side?

It's supposed to resemble a leisure suit.

On some of them, the program graphic on the front and info on the top / back is a big sticker that was stuck to the box. This is the case with my copy of Airport '77 on DiscoVision.

RCA had a better idea with fitting the center of a film poster inside a big circle.

The whole thing is weird. From the Spirograph deal at the very beginning to the busy "in case you didn't see it on the case" discovision intro, the format branding is a train wreck... Even to the point I keep rewinding to watch it.

I have some Donald duck disc . It was purchased from Video Concepts in Dallas.

Scott Strang That's awesome! I'd love to own at least one of each the more widely available video and audio formats for myself when I start work in the fall!

Or Ed might have had a Red Bull before rolling the intro. 🤣

That was Pioneer's standard dead side, starting in 1981 til the end of the format.

or maybe it was the half-assed clouding...

@@imrustyokay Well, if the clouding is still preventing the disc from being played as intended by DiscoVision despite the effort to clean it off, then it's hardly half-assed. Just saying.

It's what all the kids are listening to these days. They sure like that jazzed up be bopping music.

@@dougbennett8592 Wow, I don’t know if you’re pretending to be a senior or if you are an actual senior.

Or, D----y.

lol

This wouldn't affect certain players, such as the LD-660, which doesn't care about control codes, or the VP-1000 with the frame counter disabled.

agree

*D----y

They needed two physical sides for the disc to work, so they just slapped on whatever was laying around.

Those were rejects or unreleased titles.

I was feeling groovy! Felt like I was on aisle 5 looking for the General Food's International Coffee

It wouldn't fit. It would have to be a giant one, so it would fit a 12" disc (the same size as an LP).

It was cheaper to use rejects as dead sides and cover them in a lacquer.

@@und4287 exactly true. I worked at DiscoVision in Carson CA 1981 and we had more rejects than good pressings. quality control was difficult.
