'[PICLIST] [EE] LCD Panel pinout?'

    Hello I was wondering if anybody could help me get the following LCD
panel working (with a PIC of course!). Markings on it:

Seiko I F2426 DA

It has four major chips on it, three SED1600F (segment drivers I think) and
one SED1610F (column driver I think. It has a 12 pin header. 8 of those pins
seem to be routed together so I assume this means it is an 8 bit data bus.
The other 4 pins are a mystery though. I'm sure I might be able to figure
out which two are for power but the other 2 I have no clue, latch perhaps?
Clock? Anyways, any help with this would be most appreciated. I have
searched the web but have come up with nothing. TTYL

From the description it sounds like a graphic LCD with drivers but not a
controller.  The other 4 pins will be:
pixel shift clock,
line clock,
frame clock, and
M, which is toggled on every frame clock to ensure pixels are driven with
AC.
The 8 bits are pixel data

Someone has driven such a display with a PIC.  I dug up this link,
http://www.ednmag.com/reg/1998/021698/04di.cfm, which is no longer active.
Useful eh?  Anyway it was a weather machine of some kind.  I had a go at
this once, gave up.

    Hmm, all of a sudden this display is looking less and less useful! :(
Would you know where I could find data sheets for the chips? I tried Epson
but they don't have them any more. Do you think it's even worth me pursuing
this? I bought it for $5 for a surplus place in the hopes of using it so it
wouldn't be the end of the world if nothing came out of it. The only
question I have is that you don't mention any source of power, are these
displays powered through the clock lines or something? Thanks, TTYL

David and Herbert:
I put some graphic LCD information on my personal Web page at:
http://www.idcomm.com/personal/ottosen/

Look under "Display large characters on a graphic LCD" for the details.
You will find out how I drove the display using a SX microcontroller as
well as some data sheets on graphic LCD panels.
