Was it an issue that Infocom had been shut down? For example for making a version of the Z-Machine for Windows 95 or whatever was current. Did Activision have an archive of all the Infocom development stuff, or were you able to go off of whatever documentation fans had come up with when they were making unofficial Z-Machine interpreters?
Activision bought Infocom. We did have an archive of the Infocom servers which was kind of amazing. I remember notes for an adventure game set on the Titanic. There was a design document for Leather Goddesses of Phobos II.
