The 286 was a little before my time, although I did spend a lot of time in the early 90's hacking on a 8086. It is always amazing to me that even in the 80's, Unix used to be considered an astoundingly heavy handed OS. Now with it legacy mostly living on via Linux, it is considered the light weight alternative. Funny the path these things take.
When I got my first 286 very little was available to me because it all had a cost. Want to learn C then get your wallet out to buy a C compiler. Want to learn Pascal then get your wallet out for Turbo Pascal . Want to learn UNIX, well hard lines, that stuff is only available in ivory towers.
