   NO. Upgrading to 64K VDC RAM will have no effect whatsoever on the
resolution or legibility of the display. Since DesTerm is using the VDC
in text mode at all times, 16K VDC RAM is enough room for the 80*50
display and the character set.

   You may find that playing with the brightness and contrast controls
lessens the jitter significantly, and some colours tend to show worse
than others. Failing that, a larger monitor with high persistence
phosphors should give a nice display... if you happen to have one
lying around!
