As mentioned at the #SFRuby meetup, I'm looking for your ancient #Ruby binaries!
The oldest I have thus far is Ruby 1.4.0 on Cygwin and Ruby 1.6.2 for Cygwin, MS-DOS DJGPP, and mingw32.
I know there are weirder platforms with official binaries. Ping your #Japanese #RubyFriends! :)
My plans include running these on weird Japanese PCs at places that retro computers show up.
