No one has yet answered these in a satisfactory way, IMHO, so I'll jump

It's a single-processor 67MHz POWER-2.  It should be faster than 
everything you've got listed if they've only got one processor (well, I 
don't know what a Sony NEWS 3710 is...).  The bus is faster, the memory 
bus is wider, it's got loads of cache, and can do up to 4-way 
interleaving of memory cards (which is ECC + a spare bit).

No.  In every version of AIX I've used, from V3.2.5 to 5.2, you have to 
have install media in order to reset the root password, unless you can 
r00t the b0x with some exp10i7z, m4ng. :)  Doing that with RSH is how I 
changed the root password on my SGI Indy.

5.1 is the last version to handle every model of RS/6000.  Starting with 
5.2, you lose support for everything that isn't CHRP or a PCI-bus based 
POWER(-3/-4) system.
