I think that only one ( the PIC ) is a real show stopper.
The CPU appears to have no "smarts" in it.

Actually, that chip also does the primary booting and register mapping, so if its dead you cant boot at all,
however, its a simple memory chip
so should be able to be read and written external to the board,
if the service person has the right setup.

- If your friend still has the scope have him contact me offline and perhaps we can make it right for him, so he can enjoy the evening sky again with his instrument. I repair the Classics.

> The parts shortage, or perhaps the unwillingness to support older scopes has already started at Meade. A friend from Erie, PA recently arranged with Meade to send an 8 inch LX200 Classic for repair of a runaway VA drive. Meade accepted advanced payment, sent him an RA number and he sent it in the original foam packaging. Meade accepted it for repairs and then notified him that they couldn't, or wouldn't repair it. They gave no reason.

He is a very respected astronomer in the Erie area and I am certain his opinion will sway a number of customers away from Meade. I have been persuaded by his experience that Meade will not be there to support me when I have trouble.
