Yep, but it lacks a MMU so memory protection and paging are going to require a lot of work. I think the only reason this is feasible at all is they're running the OS out of a ROM cartridge.
Did the minicomputers of the time have MMUs?
I thought UsagiElectric showed a case where his Centurion didn’t, but I may be misremembering.
The PDP machines that Unix was developed on had MMUs, which they needed because the 16 bit processors couldn't address the multi-megabyte address space the hardware supported.
I'm pretty sure the Centurion doesn't run Unix.
