I have been using DBArtisan since 6.0. The all new 8.0.0 version is awesome. Though the readme says that they support from SQL Server 7.0, 2000 and higher, You can use this to access 6.5 SQL instances as well.

I am very much impressed with this tool. Specially with this new version, Analyst Series will be very very helpful.

Let me know if you have any specific questions.
