It's not
stretching it at all to consider the Norden to
be an analog computer. I'm not really sure how it could
be considered to be otherwise.
IBM had a Norden in its (internal only) computer museum,
so that helps support the claim of it being an (analog)
computer.
IIRC, Frank Fink has a few of these, and he told me he's
always looking for more...
