[rescue] DEC AlphaServer 4100 5/300 Questions

Hello all:

I just rescued an AlphaServer 4100 5/300 with 2 = CPUs and 512 MB RAM.  The 
drive in the StorageWorks shelf has been pulled.  Now I have a few questions:

Does this use a special keyboard?  With a standard ps/2 keyboard, the "y" and 
"z" keys are swapped when at the SRM console.  Also, other keys do not display 

I would like to run a version of DEC/Compaq Unix.  Will this box run Tru64 UNIX 
Version 5.1B-1 or 5.1, both of which appear to be available as "Non-Commercial 
Tru64 UNIX Technology Enthusiast package" from HP?


There is a note that the DEC 4000 support was removed from the 5.1B-1 version. 
Are earlier versions of DEC/Compaq UNIX available that will run on this box?

Also, the second of the two power supplies has a fault according to SRM. 
Research indicates that the second PS is a spare when running 2 CPUs.  I suppose 
that I can remove the PS to clear the fault, but does anyone have a spare 
H7291-AA power supply available?

I'm sure that I will have more questions as I work with this box, but the above 
will get me started.

Thank you,
Martin Marshall
