Im unable to get any connectivity to Oracle 7.3 using the current SSMA from Microsoft. There is no legacy download anymore and i think i need an older version, 6.0. I keep getting two-task connection potocol errors when I use the tnsnames method to define a service. This works with the schema manager in the legacy oracle tools but no matter what i try Im unable to get a connection in the new SSMA without seeing that error. I should say im on a windows 7 vm for legacy reasons.
I have tried using a linked server in sql 2008 and 2012 which would allow me to make views. I could then bring it into Entity Framework, which is the ultimate goal, but same result as above.
Anyone had a similar issue and happen to have an older SSMA?

I installed Oracle 7.3 very long ago in 1996 :).
