Really old CPUs (486 or earlier) lack the computing power to do SSL at any decent speed. So you’re limited to serving http, gopher, nntp, or telnet. Maybe IRC.
You could have a modern computer handle the SSL connection and proxy requests through to the antique but some of the purity of the thing is lost by doing that.


























You could use apache to create a webdav share. I bet there’s a pre built container for it.
Webdav is really underrated, imo.
