I'm after any version of Bentley Microstation of the Macintosh.
Before you ask: Yes, there was a native Macintosh version for Mac OS classic:

The last version was Microstation V5.0 SE released in 1997.
A version of Microstation 95 also exists for Macintosh.

I am of the understanding there was a security dongle for the application too. Does anyone have the installation disks they can image and bonus points for a [k]?
