I got a group at work to buy a Logical Microcomputer Co.
32016-based system, it originally came with GENIX, I think.
They later changed to XENIX. (I may have the order of those
I cloned the whole system on wire-wrap boards, and it
My memory was probably a bit slow, and the system was a
DOG!!! I was also not a Unix guru, by any means, so a lot
of stuff was painful. But, compared to my Z-80/S-100
system, it was so slow as to be a real pain in the neck.
So, there were several versions of Unix derivatives for the
32016 family. Nat Semi also had cross compilers that ran on
the VAX and would compile C, FORTRAN, Pascal and assembly
source into binary that you could download onto their
development boards. We built a multiprocessor system that
added on to a VAX 11/780. But, it was too cumbersome for
our physicists to go through all that hassle, and we had no
debugging facility in that attached processor mode. (I
could have hacked some kind of error message queue to the
