I still do have the book and floppy disk from the 1.0 version somewhere
in storage. At the time it had a restrictive license and I had Sun and
HP systems to play with at work so I have not done much with Minix .
Later on I moved to Linux and forgot about Minix until I learned that
Intel implemented Minix in their processors ME which was a big surprise
(Indeed even for Tannenbaum!).

Grtz.
