Digger was originally created by Windmill software in 1983 and released as a copy-protected, bootable 5.25" floppy disk for the IBM PC. As it requires a genuine CGA card, it didn't work on modern PCs.

In 1998, I created Digger Remastered, which runs on all PCs with CGA or better and plays just like the original. It also has many new features, including:

* Exit button
* Optional VGA graphics
* Recording and playback
* Real time speed control
* Keyboard redefinition
* Gauntlet mode
* Two player simultaneous mode
