Just to muddy the waters some more there was also an EC variant¹ of the 030 without the MMU.
The EC variant was available right through to the 060, and I'd be curious to know how prevalent the line was. I suspect the EC versions far outnumbered the "full" chips, because they appeared in all kinds of industrial systems. I'm basing that entirely on working for a company that was still shipping products with MMU-less 68k and coldfire this century, not any real data.

- kjs3 3y agoAnd there's more mud to be found! The 'EC' version of the 68040 & 68060 was "no MMU, no FPU", and there was an 'LC' variant of the 68040 & 68060 that was "MMU, no FPU". There were huge numbers of embedded 68k family chips shipped, although I've never seen the actual numbers. Folks went from 68000 to 68ec020 to 68ec060 as a (sorta) easy upgrade path. They're still made if you count the 68sec000, and the 68300 line is the spiritual successor.
