That's not true.
The Sun 386i Workstation was officially launched in April 1988, having been under development for more than a year prior to that date, independently of Tanenbaum's book and Minix. It ran SunOS 4.0, which was a derivative of BSD.
On a slightly different train of thought, Bill Jolitz's port of 4.3BSD to i386 was released in early 1992. It was called, at first, 386BSD, later became FreeBSD.
