Yeah, they do -- they've got the full 68030 with built in MMU. The SE/30s came out in '88, and I don't think Motorola were making the 68030EC, or whatever they called them, back then.
AFAIK, Apple's '030 machines have always had the full '030, as MacOS >7 has virtual memory support, and requires the MMU for that.
