Back in the day (early 1991) just before Linux appeared I convinced my company to pay for a copy of Coherent and they agreed. It was $99 and I learned a decent amount of Unixy basics on my el-cheapo clone 386 PC. In summary it was a pretty decent learning tool. I managed to get it to connect to my ISP and get some basic text based internet kinda things done. I eventually filched a copy of SCO Unix from a customer (which is what I had to support way back then - along with SCO Xenix) with a license key and ran that for a bit and once Linux became a bit more stable (for me it was Slackware circa 1994/1995) I started running that instead. I kinda wonder what would have happened if MWC had open sourced Coherent back then (provided they owned all their own code, or the third party code was compatible with GPL/MIT/et-al)?
