Converting very old version of illustrator

Hi,

I have very large group of ai files that starts with this:

     %!PS-Adobe-3.0

     %%Creator: Adobe Illustrator(TM) 6.0

     %%AI8_CreatorVersion: 8.0.1

     %%For: (a) (@home)

     %%Title: (A1.ai)

     %%CreationDate: (16-04-2000) (14:44)

I think their version is illustrator 3 - not CS3 Image may be NSFW.
Clik here to view.

All I want is to convert them to JPG, the problem is that the program I'm using to convert them doesn't recognize them, though it recognizes regular ai files.

So, Is there a way to convert them to a newer version of AI, and then I use the program to convert to JPG, or maybe directly get them converted to JPG.

Thanks!, and sorry for my English.
