The man pages (and source code) of old versions of UNIX can be found at

https://minnie.tuhs.org/cgi-bin/utree.pl

e.g. ("man 1 expr" from Jan 1992)
https://minnie.tuhs.org/cgi-bin/utree.pl?file=V10/man/man1/expr.1

For more human readable output
$ cd tmp
$ cat > oldman.1
<copy and paste>
$ man  ./oldman.1
