How can I get early version of cvs!

[Alsulaiman, Thamer]

Hi,


I am Thamer Alsulaiman, a junior faculty at UIOWA. I will be teaching Object 
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 releases, 
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 software, and design 
an OO project around it.


Kindly, any pointers will be appreciated.


Thanks.
