        I have had some interesting results using a V20  instead  of
        an 8088 in my 8MHZ PC clone.  I installed it last week, with
        limited expectations, since the articles I'd read reported a
        5 to 10% speedup for most applications.

        After I installed it I noticed that most stuff was  slightly
        faster,  but  it  seemed  to me that some of the stuff under
        Windows, especially Windows Write was a lot faster.  It  may
        be  my  imagination,  but  the  scrolling  seemed to be much
        faster.  Near as I could time it pgdn and pgup in Write were
        about  1.6 to 1.7 seconds, which is no worse than editing on
        my 9600 baud terminal at work.

	Also the screen seems to keep up with my typing much better.
        there  doesn't  appear to be those annoying lags between the
        keystroke and the screen being updated I'd  noticed  before.

        I  suspect  that the cause may have something to do with the
        Shift/Rotate/Mult/Div type instructions, which the V20  does
        about  3  times  faster  than  the 8088.  If some of the low
        level display formatting logic  in  Windows  or  Write  uses
        these  instructions  a  lot, then the speedup might be a lot
        more than one would expect from the 5-10% average.

        Does  anybody  have  any  ideas  on  this?   I'd  run   some
        benchmarks, but switching the processor chips on my computer
        is a bloody pain, since the socket is  partially  under  the
        hard disk drive.

	Also running Windows off of a ram disk on a EMS board helps
	a lot too, since Windows goes to the disk often.

	Windows looks pretty good using an amber monitor with a
	Hercules clone display adapter.
