You noticed our little demo station of Open Genera running on a DEC Alpha emulator. I'm afraid I'm only a salesman of things like product literature. I can't pull stock when the divergence is too great so much of what you see before you is from the cache of a wealthy eccentric. I do have a Symbolics MacIvory portable - a pre-installed add-in board in a Macintosh Portable shell. Don't ask me how they managed that one! I have copies of Nichimen N-World here. Various Lisp machine keyboards excluding the Knight keyboard. You may be interested in a more realistic option available through mail order, the Keymacs keyboard. We do fundraise for Fare Rideau's TUNES and Loper OS.
It must have really felt like Lisp was going to take over the world back then, especially with all the hardware dedicated to it. It's sad what Gosling produced instead took over (at least for a while) due to his beef with RMS
