The Free On-line Dictionary of Computing (30 December 2018):

MINIX

    /MIN-ix/ A small operating system that is
   very similar to UNIX.  MINIX was written for educational
   purposes by Prof. Andrew S. Tanenbaum of Vrije
   Universiteit, Amsterdam.

   MINIX has been written from scratch and contains no AT&T code
   -- neither in the kernel, the compiler, the utilities, nor
   the libraries.  Although copyrighted by Prentice-Hall, all
   sources, binaries and documentation can be obtained via
   Internet for educational or research purposes.

   Current versions as of 1996-11-15:

   MINIX 2.0 - Intel CPUs from Intel 8088 to Pentium

   MINIX 1.5 - Intel, Macintosh (MacMinix), Amiga, Atari
   ST, Sun SPARC.
