Abstract
The light pen described in a previous paper has been improved in functions and made more economic in realization. The principle of operation of the light pen is unchanged: a square marker with a black cross is displayed on the bistable screen of an unmodified storage oscilloscope at an intensity level high enough for good operator viewing and low enough to avoid unwanted spot writing.
