    Re: Poor Line of Position Computer
    From: UNK
    Date: 2010 Jan 12, 14:36 -0800

    Charles Poor was my grandfather. Despite that. I will not pretend to have any technical knowledge of his Line of Position Computer.

    I spent part of Christmas at the house of a cousin up in Maine. Charles was her great-grandfather. Hanging on one of her walls is an actual Line of Position Computer. I guess it is 15" in diameter, all made of now-tarnished brass and intact except for the cursor. It is inside a picture frame with various labels and such, so one could not operate it. Presumably she received it as a present.

    My grandfather was Professor of Celestial Mechanics at Columbia University and certainly was a yachtsman. Clearly Marketing was not on his priority list. I have no clue as to who manufactured them or how many were made and how they were distributed. I hedge here as I am not clear whether it was a commercial enterprise, or perhaps just a "proof of concept" or given to friends or the Navy or what. No clue of niche markets, and unaware of targeting of air navigation.

    I can contribute nothing to the navigational aspect of this, my experience limited to a "student grade" sextant my grandfather gave me when I was in junior high school. For the record, "I have never used a sextant for navigation".
