HP 8935 CDMA Service Monitor EL Display Adapter / Converter

After a lengthy stretch of research on the EL 512x256 Planar display I finally gave up trying to get a datasheet for it.  If you happen to have a datasheet I'd love to get a copy.  Planar didn't have one or so I'm told by there rep.  After a bit of reverse engineering I was able to figure out the output to the display.  I prototyped it on a large FPGA dev board but then wondered if it would be possible to find a usable LCD to fit the frame and to use something a bit more practical to do the conversion.  I have gotten a few responses back from other 8935 owners that they might be interested in a conversion kit of sorts based on what I have done so far.  I also wonder if the E8285A has the same display. If somebody has a E8285A I'd like to know if it has the same display because that might make it worth putting together a kit.  For now I just seem to take a step further and further towards a complete solution each time I power up my 8935 and struggle to tell what input is in the lower part of my screen.

Here is a photo in case you have something similar.  (Note the pilot production tag)
