Yes, the electrolytic capacitors will dry out over time, but they should 
reform with a little conditioning. It might be safer to fire up the PSU 
by itself and check it out before exposing the other components.

The system password may have been there since the beginning, but it was 
not enforced until around V2R2 or V2R3.  You can load the earlier 
releases on an expired system.

The next problem is tape. I'm finding my old tapes are unreadable. If 
your lucky enough to get the old system running, I'd do a fresh system 
backup (cleaned drive, new tapes).

A more practical use for a 9404 would be to gut it and use the cabinet 
for something else.  Larry made a nice S/34 workbench and there was 
rumor of a S/34 keg cooler years ago.

I'm partial to the Sperry Univac 90/30 and would like to have just the 
control panel. Panels from a System/3, 360, & 370 would make a nice 
collection.
