The one and only 64 bit arch I got my hands on so far is Alpha and AFAIK
Alpha is a "true" 64 bit only arch. I was quite surprised how memory
hungry an Alpha is. I am used to VAXen. 128 MB RAM is huge for a VAX,
but a breakfast for an Alpha.

Note that WINNT for Alpha ran 32bit apps.  Most 64bit architecture
can run 32bit apps.  It just a matter of emitting the right instructions.
