Hi Guys, (this is a reply to a question on the old list)
Most of my computers have been collected from the recycling centre, so
perhaps not the best place to find working samples :)  but believe me, the
statistics below are based on a sample large enough to be too embarassing to
admit to!

58% of my C64 machines are the brown bread box
67% of the brown boxes work, 78% of the beige case models
all of the SX models work - only have three though :)
86% of the C128 machines work, though 25% I've repaired (bad RAM)
90% of the C128D machines work
43% of the VIC20 machines work (50% of the original PAL)
16% of my C16/Plus4 machines (thanks to Ruud! for the CPU)

Compared to my non-CBM machines, the Commodores seem to be very poor when it
comes to longevity. Most I assume are RAM failures due to dickie power
supply regulation....

Disk drives fair better with most types having a working status of better
than 90%, except for alignment, the next biggest problem is ROM failure.

I hope the above is not too trivial, but would be interested to know if the
above is typical.
