68030 and even 68040 were used in the Mac. There was some kind of Atari system with a 68030 in it. The 68020 was fully 32-bit with some architectural improvements, irritating limits of 16-bit displacements in register plus displacement addressing were fixed, as I remeber that doing position-independent code was a nightmare on a 68000, having to see if 16-bit signed displacements would stretch and doing horrible arithmetic if not. The 68000 VM didn't work properly because of architectural bugs to do with instruction restartability iirc. The 68010 fixed that and effectively added the first block move 'instruction' by having a hardware recogniser for an instruction pair (an ancient precursor to macro-op fusion [eg cmp-jump fusion] but the latter is at the microarchitecture level) but did little else. 68020s were slow, 68030s were better, 68040s were screaming fast and iirc had floating point. The rare 68060 was a twin pipeline device. Can't remember if it was also out-of-order.
