Yep, I'm around. Our Library here at Control Data, Silicon Valley Ops
has a copy. However, we are still rather attached to it.

Curiously enough, the cover of the Thornton book uses Chippewa 36point for
the title. I guess they knew a good font when they saw one. I quote from
the frontispiece:

   'The type on the cover and title page of "Design of a Computer -
    The Control Data 6600" is a sample of the 6600 display lettering.
    The display unit contains two cathod ray tubes and a manual keyboard.
    Information is displayed in alphabetic and numeric symbols which are
    formed on the surface of the tube. The symbols are then traced out
    or "painted" on the phosphor of each CRT by the action of its electron
    beam. Control of the beam for this purpose is provided by electrostatic
    deflection in two dimensions, horizontal and vertical.
    A symbol is painted by electronically converting from the symbol, as it
    is stored in the computer, to deflection voltages applied to CRT.
    The letters appearing on the cover of this book were photographed
    from the display unit.'
