   Nice haul.  I have one of these systems as well (badged as a
"Netra NFS") and encountered a very similar problem.

   Does yours have the integral UPS?  If so, bypass it.  Mine has
(had) the UPS and when the Ultra-1 PSU was plugged into it the
Ultra-1 portion of the machine would not power up (exactly the
same symptoms as you mention).

   You might also try frobbing the power switch on the Ultra-1's
PSU.  If some kind soul did a "init 5" on the machine, it shuts
the PSU down and the only way to get it powered back up again is
to get at the physical switch which entails dissecting the machine.

   I believe the Enterprise-150 (using my box as an example) uses a
different mainboard than your typical Ultra-1 workstation.  On mine,
I have three S-Bus slots whereas on all the workstation models I've
seen there are 2 S-Bus slots and a special slot for the graphics board.

   The power supplies are identical.

   Good luck with it!
