Well that is interesting, the naming and dating of material seemed to

I wonder what happened to the Fox-1 architecture and system as time
went on.
It would be interesting then if the Fox-2 was
PDP-11-based. That is,
did Foxboro give up on making their own hardware, take their
process-control software/OS and port it to PDP-11 hardware and then
sell rebadged PDP-11s?
It's quite curious:

seems to say that the Fox-2 preceded the Fox-1:
"Foxboro Company was my next stop. I went to work immedi-
ately on its PDP-8-based control systems. I led the team that
converted its control systems to the PDP-11 as the FOX/2 and
2A. Later, I led the team that brought the FOX/1 to market in
my first project as a department manager...
The Fox-1 was a 24-bit system.
