Like lispm, I have several working MacIvory machines as well as several native Ivory machines and several working DEC Alphas running OpenGenera. I also have others including TI and Xerox but have not yet restored them.

You can, with a bit of effort, get OpenGenera running on a Linux VM and display on a modern X server. There are a few patches needed due to recent X server changes, or just run an Ubuntu from a dozen years ago on metal.
