      Since the 68010 is pin compatible with the 68000 is it possible to just
    replace the processor in the ST and get a performace increase (the
    68010 has better microcode) ?

    Swapping from a 68000 to a 68010 on an Amiga gives an astounding 3-5%
    performance increase.  Some programs with tight repetitive loops can
    see as much as 50%, but that is extremely rare.
    
    Look around for a 16 MHz 68000 board for the ST; I know several have
    been announced.  I have a 16 MHz Amiga that truly sees 20-50% speed
    increases.

     Swapping the 68000 with a 68010 is not easy on the ST, the OS wasen't
  written to handle the 68010.  The stack is layed out differently on 
  exceptions on a 68010 from a 68000.  Also, on the 68000 a program in
  usermode can read the Status Register, this is a priv. violation on a
  68010, and generates an exception.

|     Have any of these boards (16MHz 68000) been seen in the UK?
     ...and what sort of price are we talking?
