Castle Quest from Compuserv

On an IRC channel, the subject of Castle Quest came up. Does anyone know if it somehow survived the demise of Compuserv in any way, shape, or form?

For those of us not in the know, what is it, exactly?

EDIT - Funny coincidence, just five days ago I was playing a Castle Quest for the BBC Micro. It turned out not to be to my tastes, but the coincidence is cute.

The Compuserv Castle Quest is a text adventure basically like Zork1 except in a castle in Transylvania and you have to kill the vampire who resides there … astleQuest

It’s been asked before, it seems. “Bob Maples’ Castle Quest” seems to be rather highly sought after!

EDIT - Wow, there really are quite a few places where everyone is lamenting not being able to find it!
