Which distro can anyone recommend for low end hardware ?

[Oren Beck]

Ok folks- This one is not the usual "could have googled for it " question .

A day care center worker wants to buy cheap used hardware and have me or 
someone else make it work .
This center is a not-for-profit so Surplus Exchange is a viable hardware 
source .
Here's where KCLUG can come in . Showing that Open Source is truly 
viable for this person's need .
What is needed ? Single user single desktop maybe not even networked or 
if so only at the printer share level Compatibility with Msword and 
Excel in both directions , Printing flyers . Archiving all flyers etc .
Likely this system may never be internet connected !

So from that outline- What distro is suggested,
And more importantly why ?

Presently owned system is a P2/200 with 64 meg ram and 840 meg HD .
Suggestions for what to use on this would be appreciated from anyone 
having had experience with the suggested distro.
