No 020 has an on-board MMU. the EC020 comes in different packaging and has

An A1200 question: what's the difference between the 68020 and 68EC020?
I believe the 'EC' version is for Embedded Control, and lacks some of the
functions of the plain 68020 (probably MMU-related or something).

IIRC, the 68020 as a whole lacks a MMU. I want to say that the EC version
lacks some instructions which then have to be emulated in software by the
AmigaOS, but I don't seem to remember for sure. I know that's the case with
the 68060, so I might be getting it mixed up with that.
Nope, instruction set is 100% complete.
