[TenTec] Orion LCD screen darkening

[Bob Henderson]

My own opinion FWIW:

Viewing Orion's screen set for black characters on a white background places
maximum demand on the stability of screen contrast and brightness.  More
importantly in my view, it also makes long term viewing of the screen
uncomfortable.  Viewing the screen in reverse mode with white letters on a
black background is much less harsh to view and subsantially avoids the
noticeable effects of contrast/brightness changes due to temperature.

YMMV.
