    Have a Discovery 420 treadmill. On the upper PC board,
    8 of the 9 ICs have the identification info removed; it
    appears that the area which previously contained the ID
    on each chip, had been irregularly abraded with a small
    tool (such as a Dremel).

    Seems time consuming for the board manufacturer to do
    this on each board.

    Why would a manufacturer do this?
     
  2. Because they don't want anyone reverse engineering the thing.
    Because they want to be the sole repair source.
    Because they're jerks.
    Because they don't want any future business. :)
    etc.

    to keep you from repairing it. most likely using common
    components.
    also it helps to keep others from duplicating the
    product.

    The thing is, it's fairly trivial for an engineer to identify the components
    in most cases, particularly for IC's, it just makes it a lot harder to
    service.

    My treadmill (different brand) has been similarly defaced.

    Because governments allow them to. These despicable practices are just
    one reason why some equipment is uneconomical to repair and is
    consigned to landfill. If the useless, whale watching, tree hugging
    Greenies had any testicular fortitude, they would lobby for
    legislation to make *complete* service information compulsorily
    available in paperless format from manufacturers' websites or from CDs
    included with the product.
