And, wow, do i miss the old X-window workstations...well, i should clarify that i LOVED those (I think they were Sparc?) workstations that ran Solaris or SunOS back in the day! Man, that takes me back some years...but i really loved those machines! :-)
OpenBSD supports sparc very well and is compatible with old sunos stuff (iirc). Unfortunately no 68k anymore (okay, technically there's a niche flavour of 68k that still is supported because of a very dedicated man in Japan)
Kenji Aoyama truly is aligned with the best of the hacker spirit. As for getting your hands on a luna88k, I have no clue. The only thing I managed to find was a broken one that sold for ~USD 750 at an online auction.
It's worth mentioning at this point that one can still get (Open)Solaris descendent operating systems: OmniOS, SmartOS, and Tribblix. The latter still has SPARC in its installation guide.
Another part of my nostalgia with those old workstations (besides the core OS) was the desktop environment, i think CDE or motif or something like that. Something about the look and feel of that DE i always thought was cool!
