The old "archie" search engine is available once again at serialport.org via a special web interface!
The URL is https://archie.serialport.org/
Watch the full story of tracking down old internet programmers and sysadmins, of the rediscovery of archie source code in Poland and of installing it on a server, on this youtube video:
For now this archie indexes freeware archives saved on hobbes.serialport.org
The archie server currently indexes 3 other ftp sites of the serialport project:
ftp.freebsd.org
ftp.dbit.com
ftp.adobe.com
For some background reading on archie, see the relevant article in Wikipedia.
