Reading or converting ACAD2000 files

Anyone know if there a way to read Acad2000 files with Rev 12 or a generic
CAD program?  Or a way to convert the Acad2000 files to a generic format?

Or.... is there a 3rd party program that I can use to read Acad2000
drawings?

I know this is a strange situation, so pls spare me the "Wow! You're still
using R12?! I mean what a moron!" comments.  Without going into the whys
and
wherefores, that's what we are up against in this situation.

Any help would be greatly appreciated! Thanks.
