Sounds like a good project. Version 7 was where the flood gates of UNIX finally opened. Even Microsoft had a version, 'Xenix', which eventually became SCO UNIX.

Sounds like a good project. Version 7 was where the flood gates of UNIX finally opened. Even Microsoft had a version, 'Xenix', which eventually became SCO UNIX. I sometimes wonder what the world would be like if Microsoft had continued in the UNIX universe, instead of in their own isolated development. Coherent was the v-7 clone by the Mark Williams Company that introduced me to the wonderful world of UNIX. It's now open-sourced, and I have used it in a Linux x86 VM.
