You could add a 68851 to a Macintosh II, I didn't think Apple developed their own MMU for it. The Lisa had a custom MMU.
- WillFlux 5y agoAh, I misremembered. Wikipedia's Macintosh II page says: "The machine shipped with a socket for an MMU, but the 'Apple HMMU Chip' (VLSI VI475 chip) was installed that did not implement virtual memory (instead, it translated 24-bit addresses to 32-bit addresses for the Mac OS, which would not be 32-bit clean until System 7)."
