Comment on The Road to MS-DOS 2.0

Traditional reference how Microsoft was doubling down on UNIX with Xenix, before having a change of heart.

Xenix was targeted at a hardware spec that was well out of reach for the ordinary home PC consumer. The amount of ram and HDD needed to install and run it would make a computer in 1985/1986 money equivalent to a $12,000 desktop today. They always knew they needed to keep developing DOS for the low end.

Sure, but as the article points out, had it not been for the change of heart, Xenix light could have been something like Coherent.

Having learnt UNIX on Xenix, I know how expensive it was, we had a single tower that the teacher carried on into class, while we in groups of 2 students had about 15 minutes time slots to try out our applications that we prepared on MS-DOS ahead of time with Turbo C 2.0.
