    Tandy 1400LT LCD/Citizen CG-640200CG

    I ripped this LCD from a TANDY 1400 LT today. It appears to have a controller(not located on the mobo). However, I cant find the spec sheets for it. Googling "CG-640200CG" didnt get much either. Any help is appreciated! I want to control this LCD via a CGA video card. If all else fails I'll take the blue el sheet out of it and put it to good use :D.

    I did get this much:

    1400 LT (250-3500) Video Specifications


    Built in LCD display (blue)


    Optional Ports: DB-9 RGB & RCA composite


    Video Mode: CGA compatible
    Backlit Supertwist LCD
    640 X 200 pixels
    80 X 25 characters

    Dot size 0.335mm X 0.475mm
