I have a machine that old - it worked last time I used it. Perhaps we can try at the next workshop? -Ian On Thursday, July 28, 2016, Jason Perkins via vcf-midatlantic < vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
Yes, some of the discs have a touch laser rot... at least a visible colored wave. None are extreme though, not as bad as this:

Here's what one of the discs did in my player. When the machine reached a bad spot in the disc it would give up after a moment. If I used the jog control sometimes I could skip over the bad part:

This was one of the older discs, but despite having some rot it still played acceptably:

I've got some late 70s / early 80s General Motors laserdiscs that I want to capture, but my 90s Sony player won't read them. I'd like to try the discs in a 70s player to see if there's any hope of getting them to play, but don't want to drop $$$ on a player when I'll only use it 4 or 5 times. Does anyone on this list have a working player from 1984 or older with a gas tube laser? The GM dealers had Pioneer PR-7820's, I'd think that has the best chance of reading the discs. Thanks,
Did you inspect the discs for laser rot?
