BTW how different is the 3rd edition from the 1st? I had it for my OS course (along with the Silberschatz book), but it was >25 years ago. Still have the Minix disks somewhere, I think. It was awesome to get a # prompt on a 8086, but in the end, what mattered was to have GNU utils, gcc, emacs and X11 on a 386, which meant Linux.
