In May, 2006 Lic. Edgar J. De Cleene suggested on squeak-dev to collect necessary changesets, make them run in latest Squeak, and save them for future in a community effort. Edgar also collected most of the changesets needed and put together functional 3.9 changesets, I started converting them to Monticello. Please see details of each MCZ file for history of it's creation. There are 2 Monticello Projects so far, more will be converted in the future.
To run something interestingly graphical, install FunctionPlotters and see examples below.
