Josh,
I've gone through the diagnostic routines for the 5110. It seems to be
pointing to a bad H and/or J cards. At this point, I at least know the
graphics card is OK, and probably the R/W Storage cards.

I?ve had a couple of 5120s go through my hands with failed ROS boards. If you?re just
getting garbage on the screen, though, it could be indicative of something else having
failed. I do have a spare set of boards (with only one bad ROS board :)) if you need some
spares?

I've opened the machine up and re-seated all of the cards, but with no
change in behavior. Anyone have some wisdom for me on the 5110?
Thanks!
