Modern, high contrast 40x2 character LED backlit LCD screen.
 
These screens are a cost effective easy replacement for the standard (and usually dim) green standard LCD. 
Screens are the same for both the S950 and S900 machines. 
 
- Easy install - plug and play.
- Great contrast, existing contrast knob works on the new screen.
- No more inverter noise as it's not needed anymore.
