Nelson. Good question. The status is unknown last I knew. I’ve personally lost track of
anyone at Tek that might have able to help.
Also your version seems to be pure FORTRAN-IV not the mortran sources. Part of my
question is I’m not sure if they shipped the pre or post processed version. Somebody like
Ed Post (of the old “Real Programmers don’t write Pascal, they use FORTRAN”) might
remember.
Sent from my PDP-7 Running UNIX V0 expect things to be almost but not quite.

In our PDP-10 TOPS-20 archive of what was then utah-science, later
science.utah.edu (a domain now owned by our Dean's office), I find
these files:

The Bitsavers code at
http://www.bitsavers.org/bits/Tektronix/PLOT_10/TCS_3.0/plot10.ftn
has a 1974 copyright date, so our code is two years newer.
The question is, what is the copyright status of this code? Has
Tektronix (https://www.tek.com/) made any statements about releasing
it to the public?
I no longer remember the conditions under which we got the PLOT 10
code, and any licensing paperwork has long since gone to recycling.
