wow, a Genera Lisp OS -- now that is cool. These are OS's you've used, or you worked on?
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.
