[ltp] installing linux on IBM tp 600

[Nils Houben]

Hi there,
I am totally new in the linux-world. This year i start getting 
linux-lessons in my school - so i want to have my own linux to test the 
things we do in school.

My Thinkpad 600 has 500 Mghz and about 150 MB RAM, the question now is 
which linux to install, and where to get it!
As i said I am totally new to the linux world, but i am very curious and 
optimistic about linux. Though i need an easy to install linux and it 
should be relativly small (the hdd has 4GB).
I would be very thankful for any help in this case.... 

best regards
    Nils Houben
