Ground wire question

My old home (50's) has, for the main part, no ground wires running to the
outlets. The wiring is romex, but, only a hot and a neutral except where I
have added additional outlets.
The previous owner has placed three hole (grounded) outlets on many of the
two wire circuits. I know that is not to code and should be converted back
to groundless plugs.

Question: Can I simply run separate ground wires to these outlets. Almost

Yes, as per NEC 250.134(B) exception #1. You can access the 2005 NEC
online through a java applet via:

all of the wiring reaches these outlets via the attic crawl space. Do I
need to make 'home runs' to each outlet or can I install splice boxes in the
attic and do radial runs from therein?

Home runs are not required. For a retrofit application like this, you
could daisy chain all the equipment grounding conductors (EGC) in a
single run.

Cheers, Wayne

All advice or criticisms appreciated.

id do only the ones needed, most things dont have a ground prong
anyways, computer, fridge strove, washer thats probably about it. most
of those have a metal shell is why they are grounded.
