Hi, I have a Compaq Deskpro EP/C466 with an Intel 810 chipset. It is a
Celeron 466MHz with 256MB RAM. I am looking on the net about upgrading
the processor to a Pentiun III but couldn't find anything. It is too
difficult because it is an "old" computer.

Can I put a Pentium III processor on it? What is the maximum speed, if
is the case of an upgrade?

Here are the information on the hardware (from PC Wizard 2006):
