I'm sorry to hear about the Sony; I have a Sony LDP-1500 model I've not 
run in years. I'll have to check it out. If others bring their laserdisk 
players to Infoage, maybe I'll bring mine for sale.

Matt: an old trick to restore HeNe laser tubes, is to put the tube in a 
plastic bag and fill the bag with helium. Yes, the helium will leak out 
of the baggy, but it will hold for a day or so. That seems to be 
sufficient to restore the helium lost from the gas tube. Comments?

Also: I think the topic of laserdisks is marginally "on" for vintage 
computing. Early commercial video arcade games used laserdisks. I think 
the first was "Dragon's Lair" if memory serves. Laserdisks were 
supported by personal computers in the era as used in education - 
commercial, military, and K-12. (My Sony model has a serial? interface 
and some kind of command set.)

The vintage arcade collectors/restorers are important members of the 
vintage computing community. Many of the dealers, offer vintage digital 
parts that cross over to 1970's-80's vintage computers. They are active 
in the emulation community of course; many also own vintage computers.

For myself, early on, I had a summer job repairing those early 
microprocessor-based video game boards. I also had a contract job, 
documenting software which supported a set of training videodisks on a 
PC. Laserdisks (and RCA's SelectaVision Capacitance Electronic Disc or 
CED) were an important development in multimedia computing for industry 
and home.
