    Have a part on a display / control board from industrial equipment, marked
    with:

    UCN 4815A

    date code in 1984 and manufacturer icon of a stylized capital "A" (very fat,
    almost just a triangle). DIP-22 package.

    The only other "UCN" part number I can find is a UCN5800 series:

    http://www.datasheetcatalog.org/datasheet/allegromicrosystems/5800.pdf

    Does anybody know what the 4815 is, who the manufacturer is (or was), and --
    hope against hope -- a datasheet?

    And -- depending on the test results -- possibly a replacement part.

    Thanks.

    That's an Allegro chip. Mauser has them.

    Yeah, I didn't mean to imply that you should buy from them just to show
    they were still around.

    You may try your luck here:
    <https://ia600804.us.archive.org/5/items/Sprague1984DataBook/Sprague1984.pdf>

    Seems to be from a family of devices for VF display driving.

    On parent page <https://ia600804.us.archive.org/5/items/Sprague1984DataBook/>
    you will find the book in other formats.
    These may be easier for text searching.

    Cheers!
