Wow, I never knew that, small world. I have very fond memories of Coherent. I split the license cost (a whopping $99 bucks) with a buddy, both of us making near-minimum wage as bench techs for a used computer shop in Atlanta (which, much to my shock is still in business today). A few months later I scraped together enough money to pick up a used Sun 3/60 running Sun OS (and shortly after that, moved to an early version of Slackware), but Coherent will always be my first Unix.
