I'm looking for the datsheets of these LCD drivers: T7900 and T7778 , both from TOSHIBA.

The T7778A has 100 pins and the T7900 has 92 pins.

They are on a 640x400 monochrom graphic LCD:

HLR1010-10-1101 ASSY HLD1010-03-0010

which comes from an old Macintosh and I'm trying to find how to use it.

Thanks.
Kyriakos

I'm having a real hard time with these!
Here is what I have so far. These only mention your chips but, it is something.

Thanks hotwaterwizard,
I had not found the last pdf you found. It's one more clue!

It seems that the Toshiba LCD controller T6963 can control those ICs. I'll have to emulate this controller's signals to see if it can control my LCD in any way.

I've seen this one but its too general. I'll have to combine all these info and experiment a little.

Thanx,

Hey Kyriakos / AVRFeakMan, did you ever have any luck driving that LCD?  I have an old monochrome IBM PC LCD display that I'm curious about making a driver for.  It has a bunch of the L7778a and L7900 modules on it.  

That lcd_display.txt looks to have some very helpful info. 

Anyone know where to find data sheets for the Toshiba L7778a and L7900 modules?
