Nintendo: lots o' metal... for shielding?

    Decided to take apart my old Nintendo (from ~ 1987) to try and clean
    the contacts, and see if it would work. (Often, if you put in a ROM
    cartridge, the game wouldn't work. I heard on the net that it's
    because the contacts tended to corrode.)

    So, I took it apart, took out the black contacting mechanism, and
    rinsed it with 409. Dried it, and it seems to work better now.
    (Haven't played Zelda in maybe a decade!)

    I noticed, though, that there was *a lot* of metal covering the
    electronics guts of the Nintendo. (Almost cut myself with all that
    metal.) Is this to avoid broadcasting interference, or to avoid
    receiving that "interference that could cause undesirable operation" as
    per FCC rule Part 15?

    Yes. I imagine it hasn't got a metal case ? That would otherwsie normally serve
    the same purpose.

    Almost always it is to prevent the unit from radiating RF interference
    as per FCC specifications. I once helped design a device that radiated
    so much RF that we joked about simply applying for a boardcast liscense
    instead ;>

    It's got a plastic case. I would guess the metal is steel, then?
    (Searching for a magnet...) Yup, it likes magnets! So it's not
    aluminum... was kinda heavy to be aluminum to begin with, and anyway,
    they wouldn't waste the money on it... could be tin...?
