Help identifying mystery Unibus board

[Josh Dersch]

Hi all --

Found this in a stack of boards, and I don't know what it is, other than
that it's Unibus -- there's a logo but no text identifying the board or the
manufacturer.  Anyone recognize the logo in this picture?

Here's the full board, for reference:
