I just read chapter 1.5.1, Virtual Memory, of the 68020 Manual (see
http://ebus.motorola.com/brdata/PDFDB/MICROPROCESSORS/32_BIT/68K-COLDFIRE/M680X0/MC68020UM.pdf),
and wonder if it would be possible to emulate a MMU (68851).
Machines without one (e.g. the Cisco IGS) could benefit of that.

I understand that it would be slow, but would it be doable at all, or am I
missing something important?
