Run an issue of TUGboat

Hi all,

I’m new to tex and I’m trying to run an old issue (15) of TUGboat. For that I’m using the files

tbcv15.tex
tbcont.def
tugboat.sty
tugboat.cmn

When I run tbcv15.tex with TexShop I get this:

This is pdfTeX, Version 3.141592653-2.6-1.40.26 (TeX Live 2024) (preloaded format=pdflatex)
 restricted \write18 enabled.
entering extended mode
(./tbcv15.tex
LaTeX2e <2023-11-01> patch level 1
L3 programming layer <2024-02-20>
(./tbcont.def (./tugboat.sty File `TUGBOAT.CMN' v1.30  <2024-04-15> 

What am I doing wrong?

Thanks,

Franck
