The NS32016 (nee 16032) was the 16-bit bus member of the family the
32032 was nearly identical to the programmer. The later members
('332, '532) were better integrated (on-chip MMU), but not very
different.
Sequent had NS32016, NS32032 & NS32332 Multiprocessors running DYNIX
(BSD 4.2 based).
The Symmetric 375 (32016) ran a BSD port (by Bill Jolitz)
see

The Whitechapel MG-1 (NS32016) ran Genix
When I worked at BU we had many Multimaxes (Multimaxen?) which were
32032 (APC), 32332 (DPC) and 32532 (XPC) based -- they had both BSD
and SysVr3 ports called Umax 4.2 (and 4.3) and Umax V respectively.
My pc532 (ns32532) runs NetBSD (and used to run Minix).
The two guys who designed the pc532 did an earlier board (an ISA bus
plug-in) that ran some flavor of Un*x.
I'm sure I missed a few....
