I'd like to run a pretty old Linux distribution (say from 2003) on VirtualBox. It doesn't look easy to find any ISO and package sources. Has any one try this rather strange adventure?

If you look at the distro you want, have a google around their websites. As Oliver said, many of them keep older versions for you to download.
For example, I just checked that I can get early Ubuntu ISO's (certainly back as far as 2006) and Slackware. Took me about 6 seconds of googling.
It is relatively common to keep a wide range of ISO's for historical and research reasons.
