Building Joseph E. St. Sauver's tex primer for vax

[Suresh Govindachar]

Hello,

In attempting to build, using MikTeX on Windows, Joseph E. St. Sauver's 
tex primer for vax found at 
http://tug.ctan.org/info/tex-primer_vms-specific , I ran into a few issues:

1) In overhead2.tex, had to replace two occurrences of Helvetica with 
something else (used Computer Modern).

2) Appendix F ends up with a watermark of upside down F, and Appendix G 
with a watermark of G.

3) The generated index.tex needs to be transformed to something like 
myindex2.tex.

Two questions:

a) My naive attempts to replace Helvetica with Arial failed. How would 
this replacement be done?

b) Why do Appendix F and G have watermarks, and how can they be removed?

Incidentally, here's an archive of the author's own files from 2013:
