Back in the day, Atari 2600 and Commodore VIC 20 owners used B&W TV for their displays. I had the 10" RCA Sportable and my VIC looked crisp on it, especially for programming.
Whenever I crafted a new game in BASIC and later in machine language, I’d showcase it to the family on the living room Zenith 20" console color TV. Of course, the color was nice, but its bleed from the RF modulator made going back to the B&W “acceptable”.
Is there a retro shader out there, or an option to run in grayscale?
