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… -- Chris
