I need software to be able to use my Palm Pilot

Question

I have acquired a Palm Pilot that has never been used. When I opened the software, I found that it was dated 1997. Needless to say, I cannot get the Palm Pilot up and going. Can you please tell me what to do to be able to use this. Can this software be downloaded from the internet?

It is a Palm Pilot Professional I assume made by 3Com.

Any help would be appreciated.
