Emulation of MC68000 core on 16-bit x86?

Hello all,

Do you know of an emulator, or even the skeleton of an emulator, that
can do barebone MC68000 on say 80186 or 286? Speed does not matter.

Was there any emulators used when porting old 1.5 Minix to diverse
platforms, like Amiga, Mac or just scratch rewrite?

I have downloaded the simulator and cross assembler from Motorola, but
building own emulator on that means like 900 hours of work, which
cannot afford on a freeware project.

Thank you very much in advance, Faithfully: Tamas Feher.
