They gave them out on the condition that they not be posted online. If someone gets to the point on the View port where they are ready to begin writing the DAC driver, I'm sure we'll be able to get them a copy of the datasheet.
Bagder:
Other methods of finding the exact LCD controller in use have involved finding out the init sequence (by reverse engineering the Original Firmware) and then comparing that init sequence with datasheets (or code) for existing LCD controller suspects.
dram_dave:
Has anyone looked at the View's power management? The AS3517's three main buck converter outputs (supplies) shift their voltages from 1.0v / 1.7v / 3.0v in mp3 playback to 1.2v / 1.8v / 3.3v during video playback when the CPU etc. presumably need faster speed. The SDRAM clock rate also switches by a factor of 3x. Does anyone know if this was done on the e200 series (and where in the code)?

Not sure if this helps at the moment, but here's something.
Using funman's idea of Googling info on some chips on the PCB, I have managed to find a data sheet on the internet for the Samsung K4M56323PG-HG75. It's an SDRAM chip, and I found it on space_ghost's scan of the back of the PCB.
The data sheet can be found on this page:

Again, I hope this helps.

Not sure if this helps, but I removed the metal plate on the back of my views LCD and there were some numbers on the back as well as a few on the side.
I have a smashed View I use for parts and am not the slightest bit afraid of opening my good 16gb working view. I did notice however, there were different numbers on the 8gb ribbon connector for the LCD and the 16gb ribbon connector (this could be a mute point, just wanted to put it out there.)
The black numbers on the back read
TD-T240T2G120-10
S070914008
(in case they are hard to read)
and on the side is BLU120-10 A3 S70821209C
Not sure if this is a help or nothing at all, I was contacted by a Pepa.Vidlak to post what I could on the LCD, this is all I got.
