A video on Hacker News showcases the Oldest Digital Computer in America playing the Doom theme song. While impressive, some users felt the title was misleading, as it only plays the song and doesn't run the actual game. Discussion highlights the challenges of early computing, with users marveling at the ingenuity of using magnetic drum memory and vacuum tubes, contrasting it with modern technology. One user pointed out that even simple circuits required many transistors and that 8kb of memory are arranged as 2,200 29 bit words. Some viewers questioned if the computer also rendered graphics on a line printer as suggested, with others doubting its feasibility given the computer's limited memory and storage. Users estimated that rendering even a basic scene would be a programming feat. Another user calculated the impracticality of storing the full Doom game on paper tape, requiring hundreds of miles of tape. In short, while the project is a cool feat, the title overstated the achievement.
