We missed this earlier this year, but Coherent has been released as open source. Coherent is a UNIX clone originally developed for the PDP-11, but later ported to a number of other platforms, including the IBM PC. It was developed by the Mark Williams Company, and despite an official investigation by AT&T, no signs of copied code were ever found.
Mark Williams Company closed in 1995. In 2001, Bob Swartz asked me to archive the hard disks containing the Mark Williams source repository; the command and system sources here are from that repository. I have long intended to catalog and organize these sources, but in the meantime they are posted here as is. MWC’s documentation guru Fred Butzen provided the MWC documentation sources.
And it is 3-clause BSD license, so most projects can freely reuse the code. Not sure whether the code is worth reuse though.
What a painful website to look at. Oh well. Thanks for the browsers view no style option.
If I remember correctly Bob Swartz is the father of Aaron Swartz.
I never heard about that system. Cool thing. Maybe someone will pick up sources and give this a new life? However there so many UNIX clones, that chances aren`t high for that.
