Not for the typical meanings of the terms "run" and "Windows" you
can't.  You can run specialized versions of a system superficially
similar to, but internally quite unlike regular Windows, on ARM CPUs
in the 200+ MHz range.  The resulting system is called a "Pocket PC"
or "Windows Smartphone", depending on what version of Windows CE is on
it, and whether it has a mobile phone built into it.  The major
problem in doing this yourself would be that individual developer
licences for Windows CE essentially don't exist.

You may have to stretch the meaning of "possible" a bit, but: yes,
it's possible.

When you say you want to build one from scratch, what do you actually
mean?

Do you mean:
1. you want to start with a chip like the lpc2000 series processor,
etch your own 2 layer board(minimum here), design the peripherals
around that and finally make an operating system from scatch for it, or
2. start with a minimal board with a processor on it(like the ones from
olimex) and then build peripherals around it, and then uses say a OS like
uClinux and recompile it for your needs, or
3. start with a single board computer heavy in peripherals, eg. CF interface
, lcd interface, keypad interface, and much more. Maybe even have it pre-
installed with some sort of OS, or lastly
4. build a computer, read as "put a computer together" usually a wintel
box or similar.

Personally, I'm working from 2. Its not that hard, you just need to
be decisive in what you want. Cos, you can't have everything on such
small devices.

FAQs about me:
Are you looking for work and do you want to work for us?
Yes, but only if it pays.
Are you insane?
No, not at the moment.

hi,

i just saw that the new HP49G has an ARM running at 60MHz, and it got
me thinking that my first computer was a 40MHz 386DX with 4MB of RAM
and i remember i could run windows 3.1 on it. Does it means that i
could run windows on an ARM running at 60MHz (not on the calculator of
course)
could i build a computer with an ARM? (i think Acorn computers were
based on ARM) but i'd like to know if it'd be possible to build it
from scratch
thanks
