Whenever I see retro-style portable DIY consoles, they either use a Nokia-style 1-bit black-and-white monochrome screen like in the Gamebuino, or they're built with an RGB color screen like with the PiGRRL Zero. I'd really like to know if anyone is still making monochrome screens in more than just 1-bit black-and-white. I mean, is that even a thing? Or are the gray tones of grayscale-capable monochrome screens controlled elsewhere in hardware?
Is anyone still making Game Boy-style 2-bit monochrome screens?
