Tested with B089AW01-V.0 and HSD089IFW1-A00-V1.0 on a breadboard. I'm sure it will work with other displays from old netbooks.

Questions
What parts does the Analog Controller use?
42 parts, built around the LM324 and LM1117T-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Analog Controller KiCad files?
From the mwwhited/EmbeddedBakery repository on GitHub, at the commit this page was made from: the board is circuits/HelperBoards/Controller/Analog Controller/Analog Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Analog Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask mwwhited before reusing the design.
