There seems to be a distinct shortage of Ultima demos around. I suppose most of the later games were rushed and not exactly finished on release, so a demo may have been an unnecessary distraction in the circumstances. There was a non-playable Ultima 7 pre-release demo which is hosted here. A video of this was already on Youtube which I’ve embedded below:-
It consists of the intro and an ultimately optimistic claim that the game will be coming in Xmas 1991. It only has adlib music which is a bit of a letdown, and it’s not implemented as well it would be in the actual game. I imagine there would originally have been an installation program which has gone missing. The demo comes with all the music as MIDI files which can be played directly through an MT-32 to much better effect, but if there is a way to set up the demo’s config file to do this I couldn’t find it. The intro is cut down substantially from the one I’m used to but other than that there isn’t a whole lot to say about this so I’ll move on to Ultima 9.
