myDSL Extensions (deprecated) :: can i expand my old DSL 0.6.0

Hi. I am a hobby programmer and a LINUX fan. Three days ago, I find DSL 0.6.0 in my local network and I burned it on a CD. Then I read that it is possible to expand it with new packages. unfortunately it is too old version to be expanded , is it ? If it's not , please tell me a way to install .dsl or .tar.gz packages.

original here.
