The task at
hand is driving a 4" diameter vector CRT. _Any_ 4" vector CRT
What the heck is a 'vector CRT'? AFAIK such things don't exist. whether a
CRT displays 'vectors' (meaning you deflect the electron beam to a point,
turn it on, then move it along a line to display that line), or a
'raster' (meaning you scan out a series of lines and modulate the beam to
display an image) depends on the external circuitry, not the CRT itself.
Magnetically-deflected CRTs (like those in most monitors and TVs) are
generally easier to use to display a raster, but
electrostatically-deflected CRTs ('scopes, 'vector displays', etc) can be
used for either.
