The perl repository goes all the way back to Perl 1
I had been looking around for the ancient Perl sources to add to my collection, but Schwern told me that they are already in the Perl git repository. I just have to checkout the correct tag:
$ git tag -l
perl-1.0
perl-1.0.15
perl-1.0.16
perl-2.0
perl-2.001
perl-3.000
perl-3.044
perl-4.0.00
perl-4.0.36
Now I just need to get these to compile on my MacBook Air.
I've suggested that Schwern needs to make a git archive of the internets now.
I'm the author of Mastering Perl, and the co-author of Learning Perl (6th Edition), Intermediate Perl, Programming Perl (4th Edition) and Effective Perl Programming (2nd Edition).
The latest perl-1 tag will compile on modern machines. You'll have less luck with perl-2 through 5.5 or so.
I *think* there is also a perl1-on-parrot project
