<deflection coils to steer the electrons through a character stencil (like
<shadow mask), and a second set of deflection coils to steer the electrons
<to the desired character location on the screen. If memory serves, this
<type of display was used on Whirlwind. Presumably it was more economical
<than using a standard XY oscilliscope with either a hardware vector charact
<generator or software.

It was also used in some terminals and Xerox high speed eletrophotograpic
printers. The later being basically a Xerox copier with a charactron as the
image source.
