Some people in The Netherlands say that the first UNIX computer stood in Nijmegen, but this is not true. I witnessed in 1976 the installation of UNIX version 6 at the OW&OC (later called the Freudental Institute) of the University of Utrecht.
My first Unix computer was an ONYX C8002 with Z8000 processor
An AT286 PC with XENIX.
An AT386 PC with UNIX System V 386.
