Wild Hare Computer Systems is pleased to announce the public beta release of its Data General Nova and Eclipse emulator.

This emulator allows the full range of DG 16-bit Nova and Eclipse computer software to run on Microsoft Windows and Linux platforms, and will become a major part of Wild Hare's increased efforts to preserve Data General's significant contributions to computer history.

Prior Data General knowledge is beneficial to using the emulator and corresponding DG software. For convenience, Wild Hare has created container files of pre-configured operating system environments and their corresponding languages to minimize the time needed to enjoy the full DG "experience".

This "beta-level" software release is intended to gather user feedback to help guide future product development. Bug reports, comments, suggestions, ridicule and giggles can be sent to b...@wildharecomputers.com.
