LCD - Built-in Display
Path One: Keep the current LCD
Duties
If recycling the current LCD, will need to ensure proper power is available and do one of two things:
- Convert the video signal from HDMI to 4-bit monochrome LCD signal
- Write a driver that is similar in structure to SPI/I2C framebuffer to output compatible signal
Pros
- Less hardware to purchase
- Keep original aesthetic
Cons
- Difficult to get awkward and high voltages to run CFL backlight
- Have to reverse engineer old 4-bit signal standard (Documentation is minimal, but looks to be comparable to VGA)
- Writing a god damn video driver
Path Two: Use a new LCD
Duties
If using a new off-the-shelf LCD, will need to find something that will fit inside of the current case.
- Curent screen: 4:3 ratio, 9.5" diagonal, 7.6" width , 5.7" height
- 16:9 screen: 11.6" diagonal, 10.1" width, 5.7" height
- 16:10 screen: 10.8" diagonal, 9.1" width, 5.7"

Pros
- Much easier to just use HDMI/VGA and 12v power
- Brighter, easier to see
- Color!
Cons
- Damn near impossible to find modern LCDs that are the proper size
- Will need to make custom mounting hardware for the screen
- Price of a new LCD is slightly more than I'd like to spend
