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)

No 32-bit sparc anymore (only UltraSPARC, aka sparc64).

No SunOS compatibility (despite Theo de Raadt inventing it for NetBSD, before being copied by other BSDs).

luna88k, while related, is not 68k.

		I must've read about the sunos thing somewhere and imagined it still existed. >luna88k, while related, is not 68k I misremembered it as being similar to the relationship between the 6502 and the 65C816
