The MVME121 only has one.
Isn't the Sun-2 MMU also a segmented MMU, or did it support paging? I thought segmented MMUs were typical in 68000/68010/68012 UNIX systems.
I figured that with such an MMU we'd have a couple permanent mappings and just load other mappings as tasks are switched. I'll admit to not having looked at it at all really…
