  • Well, sure, but the C64 had 512 times more RAM(!), plus the VIC-II chip for graphics and the SID for audio. The TIA chip in the Atari was a joke in comparison. The CPU just isn’t that important. It only needs to run some game logic. It’s the graphics and sound that matter for games. The NES and SNES had very similar CPUs[1], too, but the graphics and sound chips are what made the SNES blow away the NES.


    1. Same instruction set, but 16-bit and clocked twice as fast, plus a few more features. ↩︎

    Pinholes diffract light.

    The diffraction effects from a pinhole camera are not what make them work. In fact, diffraction makes the photographs worse than they otherwise would be. The pinhole makes an effective aperture for photography because it’s small size produces small circles of confusion on the film plane. Ideally, you would make the hole as small as possible, but beyond a certain (small) size, defraction becomes the dominant source of blurring. So the size of the pinhole should be chosen to yield the best balance between geometric blur and diffraction blur.

    The diffraction is merely a limit to the smallness of the aperture, and not what creates the image.
