What OS was the SAS V6 catatog created under? It would have to be under the same OS you are now trying to read it. Also a V6 catalog is likely 32-bit. What bitness SAS are you trying to read it with?
You could try a test like this:
libname mytest v6 '\MyV6folder';
proc catalog cat=mytest.MyCat;
contents;
run;
quit;
Please post the SAS log from this test.
I would contact SAS tech support for suggestions. They are likely to have access to a SAS 6 version somewhere.
