Please see eBay to max out your RAM (probably PC133, needing 2X256), then go to http://linux.softpedia.com/progDownload/MEPIS-AntiX-Download-27857.html and download.
This Linux distro is amazing on lod machines and with access to Debian and sidux (and other) repositories, you will hav no trouble upgrading software, including OpenOffice. You will definitely need the most RAM your motherboard will support, however.
To find this out, go to SystemRescueCD (http://sourceforge.net/projects/systemrescuecd/files/) and download version 1.3.4.
It is a LiveCD and has a utility that tells one all that is needed about Hardware used.
Best wishes and my the Creator bless your efforts!
