Motorola 68010
     
         A {microprocessor} from {Motorola}.  It was the
        successor to the {Motorola 68000} and was followed by the
        {Motorola 68020}.  Some instructions which were previously
        {user mode} were made {system mode}, which necessitated
        patches to a few programs.
     
        The 68010's main advantage over the 68000 was that it could
        recover from a {bus fault}.  The 68000 {microcode} didn't save
        enough state to restart all instructions; the 68010 corrected
        this fault.  This allowed it to use {paged virtual memory}.
     
        The 68010's DBxx (decrement and branch) instructions could
        hold and execute the preceding instruction in the {prefetch
        buffer}, allowing some two-instruction loops to execute
        without refetching instructions.
     
        At one time there was a 68010 variant that was pin-for-pin
        compatible with the 68000.  Early {Amiga} hackers replaced
        their 68000s with 68010s in order to get a small performance
        increase.
