It would definitely be worth it. I would even go so far as calling it a _major_ tragedy if the 0.1 was lost, and would also want to urge CERN to set-up a webserver (at least emulating) running the 0.1 accepting connections on :2784 (the original port used for testing AFAIR).
Maybe Henrik Frystyk or some of the other early contributors have a copy laying about.
EDIT: Just sent a mail to Frystyk. Someone with a direct or indirect connection to TimBL should also try and contact him.
EDIT1: Apparently not. email@example.com doesn't work anymore :( Trying a different route.
