I still have 30 or 40 LD-V1000s (basically NOS) so I didn't feel too bad about tearing one of them (that didn't work the first time) apart. What I found interesting is that they use a Z80 as the processor. Also, most of the ones I have gave significant picture jitter when I first checked them out. Turned out that there is a pot inside that has a connection to where the laser is on the disk. That pot somehow got "noisy" over the past 15 - 20 years they have been sitting and a combination of contact cleaners made the machine operate as new again. And the service manual is available on-line at the Dragon's-Lair-Project website. As an aside, that website also has the diagrams to make up a centronics plug to be able to start the laserdisk playing. *REALLY* nice for checking out a unit! A friend of mine also has all of the alignment jigs in case I wanted to go that far into repairing these things.
