My evolving monograph "In Praise of BASIC".

To get it to display properly, you need to get LaTeX to recognize the Teletype font TELETYPE1945-1985.ttf as "classic" font family oty.
The following instructions work for MacTeX and should work for similarly-organized TeX distributions:

1. Locate the texmf-dist directory for your TeX distribution. For MacOS TeXLive, it is usually /usr/local/texlive/{distrib}/texmf-dist; check System Preferences > TeX distribution to see which distrib you have active)

2. As root (or a user that can write to the above directory), change into the paper's home directory and run ttf2texfonts.sh dirname where dirname is the texmf-dist directory above

3. As a regular user, you can now run make to make the pdf file, etc., and use oty to reference the Teletype font family (uppercase roman only) in your documents.
