MySQL Gurus* Help!
 

I'm trying to revive some old websites. I recently found the backup disc with all the files. Problem is* I don't know what version of MySQL the server was running. What I have are the files from the MySQL data directory and not export .sql files.
Is there a way to find out what version of MySQL created them. It has to be one of the old versions of version 3 or early version 4 maybe 4.1. Due to the changes from version 3 to 4 and changes in early version 4 to 4.1 the files are not compatible across versions* as far as I know.
