Ooh. I've been putting together a VT420 emulator and I am trying to figure out the best way to build one from scratch. I will probably end up building an RP2040 version of the video controller.
These look great, but I wonder if there's an 800x420ish version out there.

Always impressed with the PIO capabilities.
Reminds me of the old BeagleBone Black that had two small separate cores that worked in a similar way. Someone used it to create a 3D printer control system.
Are there any other chips out there like this?

These screens look amazing, but $1500-2500 is a bit much. Any other screens with this monichrome CRT style?
