What's the current drain?  I see this nowhere on the site (so far).

| Things must be really slow; I'm replying to my own message!
| 
| I just found that Lumex makes a backlight that may fit:
| 
| http://www.lumex.com/pls/lumex/subproduct_galary?iproduct_id=1001050
| 
| SSB-DL3117xxx -- xxx being color.
| 
| 30.5 x 17mm edge lit backlight panel, available in several colors
| including green. So if someone wanted to order the transreflective
| Varitronix display, and then the Lumex backlight, it may actually work!
| You'd have to bend the leads (since there are no board holes for a 
| backlight) and run power/dropping resistor. Digikey carries Lumex
| and Varitronix; maybe they can special-order. 
| 
| See below for LCD info.
