For those who may not know, #OpenBSD still runs on Motorola 88K machines, more specifically the LUNA family of 90's Unix workstations released by Japanese company OMRON. There's even SMP support (w/ weird configurations, like 3 CPUs).

Largely a passion project by Kenji Aoyama as these machines are not easy to come, especially outside of Japan. It's possible to install 7.8 (or a -current snapshot, to try out Miod's 88k gcc4 port! ​) using nono, a full system emulator for LUNA machines.
