opening old dwg version autocad 2 (r10)

[dud80]

Hello everyone, for work needs I found myself dealing with dwg files of 1989, so I suppose created with autocad 2 - r10. with autocad 2009 I can't open them. Is there someone who can tell me some solutions, some tools to open them? Thank you.

if they are not damaged files you should be able to open them normally
