On real TT HW, it gives a bus error as it seems to not switch to supervisor mode when fetching the "invalid instruction" vector (remember, address < 0x10000 can only be accessed in supervisor mode on Atari machines). This would be a bug in the 68030. On Hatari, it gives an "invalid instruction" because bit S is set (which should be the normal behaviour)
Actually, no, on Hatari this invalid instruction ("3584 6900") runs without any exception.
