I have come into possession of an old ECG machine, and have taken interest in it's screen. The screen works, as far as I can tell, and has a 4 pin peripheral connector for the backlight.
While the display will respond to input, I'm unsure of how to communicate with the screen properly. It has 12 pins, ruling out a standard LCD protocol. I came across this archived document:
here, which suggests that the screen I have (LM384CXFR) is an EGA screen, but EGA connectors have 9 pins, so I'm not sure about that either.
The LCD screen itself is driven by 10
HD61104A chips.
If anyone has any information or insight, I'd greatly appreciate it. I doubt I could get a 640x400 display running on an Arduino, but I'd like to get it running on something.
