Yes, you can, although I can't really suggest where right now. I'm
sure some Googling would turn up some suppliers, but I'm only
replying right now because I'm interested in answering one of your

Hmmmn... I'd guess otherwise. My experience is that manufacturers &
PC specifications do take compatibility a long way - take, for
instance, the prevalence of PS/2 & mouse sockets on current
motherboards, 5 years after USB was going to make these "legacy"
connectors "obsolete". For years (into the Pentium 3 generation, I
guess?) I had motherboards with ISA slots I never used. The
incompatibilities we do encounter between hardware are surely only
sacrifices that manufacturers must make in order to achieve performance.

Looking at that page there's a link to the motherboard's manual.

It says "supports AMD Athlon 700mhz - 1.2ghz or future socket A
processors based on 200mhz (100mhz double data rate)" - from this I'd
assume that you're unlikely to find a processor significantly faster
that will go in this board.
Faster socket A processors based on 200mhz (100mhz double data rate)
MAY have been released since the manual was published, but since
yours was the fastest available at the time, I doubt you'll be able
to find one with twice the clock-speed, or even as much as 1.5x. You
surely won't be able to find them in the shops, and my experience is
that eBay is too much hassle for a 10% or 15% clock-speed increment.
My experience is that once a socket implementation has been EOL'd
(end of lifed) it's rarely worth upgrading machines based upon it. PC
components are so cheap these days that you can probably get a
processor with 3x the clock speed (and the motherboard to run it on)
for as little as $100. Or £100, if you don't have any US holidays
planned in the forseeable. :( See the "help me upgrade" thread for
