[TUHS] 1980s troff help?

[Russ Cox via TUHS]

I downloaded the Sun archive, changed the troff to refer to
fonts C and CB instead of L and LB, and then ran it through
the Heirloom Doctools <https://github.com/n-t-roff/heirloom-doctools>
version of troff with no problems.
I published the results in a Git repo at https://github.com/rsc/nfs.

Specifically see:
https://github.com/rsc/nfs/blob/main/release.pdf
https://github.com/rsc/nfs/tree/main/usr/src/sun/doc

The conversion is fairly close to the scans that Jonathan Gray
posted but not exact. The released text is not always the same
as the scanned text, and the code for generating the tables of
contents was not released, so those are missing.
But overall it is surprisingly close.

Best,
Russ
