in 1990, while working for an insurance company, we were looking for what UNIX to port a multi user database to, We looked at SCO, Microport, Cohernet and Sperry. The company chose Microport, and the Sperry went back, so I got to keep SCO and Coherent. Loaded and ran both, liked SCO a tiny bit more because of it successfully compiling a few programs, and heard about the UNIX Copyright controversy. Coherent installed, and ran, but had a few incompatibilities with our software, but ran solid as hell. The documentation was very good too.
