  Because Android is Linux underneath, and we were discussing the
relative merits of Linux in general, in the context of the possible
impending orphaning of Solaris.

  Yes. :-(

  I've not worked on one, but when I managed one commercially we had
power supply work done on it twice in as many years.  Other than that it
was rock solid.

  How difficult is it to run that power supply outside of the main
chassis, have you done that?

  What are you doing for a TU58 drive on yours, did you repair it, are
you using a tape emulator, or is it by some miracle still functional?
