Since PDF didn't exist in 1981, the document is either a scan or the
result of a recent *roff run on ancient source. If it was made from
source, it's an impressive testimonial to the longevity and stability
of troff. Most probably it's a scan, in which case we owe many thanks
to the public-spirited person who digitized this trove. Was it you,

It's a scan of photocpies I made from original printed documentation.
Matt Gilmore did the scanning; I had the paper on my shelf for ~ 40 years.
It was set on an Autologic APS-5, as one can see on the second page
of the table of contents file.
