I don't know in what specific date Digger came to life, but I'm very happy that even today it is still remembered. In fact, this little old game has an official page, from which you can download Digger along with other classics, such as Styx.
Ah, the good ol' Digger was remastered and ported to several platforms, including some Linux versions! I could download the Debian version from that page!
Way to go, Digger!
