[Premium-Rx] 2050 Backplane Lighting

[Walter Salmaniw]

Fellas, as I remember things, John Bryant was one of the first to 
investigate the backlighting issue, and I do believe that he removed them 
due to EMI interference which was noticeable.  Personally, I've never found 
the need for anything like this since I never DX in a totally darkened room 
anyway.........Walt.
