That is almost everything I remember about it.
It was really short, probably old too. The early portion of the story describes the land and compares it to Xanadu, with fountains and stuff. The later part describes an evil AI/Supercomputer. There was something about the protagonist finding a port which allowed him to connect with its conscience, I think.
Sorry for being so obtuse, I just seem to have forgotten everything about it and would like to read it again. I also do believe I picked it up from a thread somewhere on this site.
