How can I get early version of cvs!

Hi,


I am Thamer Alsulaiman, a junior faculty at UIOWA. I will be teaching Objec=
t oriented design next Fall.


I am currently thinking of giving the students project on version control. =
I downloaded the CVS files from 2005. But I wish to get much earlier releas=
es, which I expect to be simpler and have basic functionality. I need it as=
 a basis to understand the basic building blocks of version control softwar=
e, and design an OO project around it.


Kindly, any pointers will be appreciated.


Thanks.
