I can tell you that although the MDA card has a light

Long persistence phospor doesn't preclude the use of a light pen, it
just introduces some limitations on the usage model. The DEC Type 30
and 340 displays as used on the PDP-1 through PDP-10 use a P7 phosphor
which has very high persistence, yet light pens were commonly used with
them.
