    What would you do with this?? Old HP plotter board

    Howdy all-

    Been busy with other things recently, but I'm finally getting around to packing up another load to send off and have a few odds and ends I might ask y'all about. One is this- the main board out of an old HP plotter:







    It has that lovely gold patch on one end, but then it has some honking big caps on it and the aluminum heat sinks are soldered right to the board. How would *you* process this??

    As always, any suggestions are welcome!

    cheers,
    thebugguy

    I'd pop that big cap off and I think if you pry on those heatsinks, the solder should pop loose to remove them. The rest looks good.

    What would it be graded as? Less than mobo? I searched but didn't see anything to compare it to.
    In general. I know its up to buyer.

    Thanks for the advice. I'm sure I can get the heat-sinks off one way or another and the two large capacitors (at least that's what I think they are) should be easy.

    Is that round, metal-covered doodad in the square heat sink a type of transistor? I don't think the sink will come off without it...

    And yes, I'm generally interested in the per-lb value of something like this, but without 50 or a 100 of them it really doesn't make much of a difference in my books.

    cheers,

    You can figure that the items on both heatsinks in the picture are transistors. The round one you are asking about is called a "TO-3" package style. It is made that way to accept heat sinks. The base of it will probably be plated copper. I can't remember what the package style is called for the other 4 transistors on the other head sink but their metal backs will also likely be copper, too.

    Look like TO-220's on other heat sink.
