You're right to be anxious your 710 to revive.
The 7xx are nice workstations...  

1/ For the power supply, you have first to consult the HP-HCL in pdf format (9MB!):
See http://ftp.parisc-linux.org/docs/980723.pdf, to extend your research.
It is preferable to acquire a standard model. If you can't, I think too a power 
supply type AT or ATX is possible (with any adaptations of connectors - Be careful 
to the Graphics Card as well). I could help you about it, if my box were 
open actually. May be, some other time.

2/ About the keyboard: It is a HIL-keyboard (much easier to find out on the World 
Market). Don't forget the HIL-mouse connected on it.
The keyboard isn't essential to boot, if you have LAN or a serial connection. 
Except, the configuration will be more acrobatic.
For instance: a PS/2 keyboard, via a RS232-adapter, could be added, but have to be 
pre-configured.
