[TenTec] Jupiter display backlight

[Dr. Gerald N. Johnson, electrical engineer]

It might be practical to create a replacement for the electroluminescent
light source from a thin sheet of plystyrene acting as a light pipe. It
would be excited by an incandescent lamp or two, most of the surface
would be polished, while the area behind the display would be frosted.

73, Jerry, K0CQ
