That post made me LOL repeatedly! I had a Yammy from the late 80's too and it grew pouty, not reading or skipping at first until it was good and ready. I'd be kneeling in front of the Yamaha praying for it to work and trying one of those lens cleaning discs that the dealer suggested, but this changed nothing. Yamaha made some crap back then, they also failed big time in the mid 80's with car gear.
