Please note that I can't confirm that Apollo used this approach - the earliest Apollo workstation I know (the DN300) used a 68010 already. I would love to hear more details on this...
I'm also not sure which approach early SGI workstations used (the Iris 1000 series), documentation on those is extremely hard to find.
