That apparently was with batteries; much less when you leave the battery
pack out.

Reading through the document, however, I wonder if this was ever a real
product and not just an engineering prototype (if that).   CDC did quite
a number of "pie in the sky" proposals back then.  Pity that they're not
documented.

Bitsavers has the 449 Reference Manual:

Weight was 12 pounds.

Thanks for the comments everyone. That article, it's a good take on the origins 
of the minicomputer term.
I could well imagine the editors of Datamation, upon hearing CD's term 
'miniature computer' shortening it to
'mini-computer' for a snappier title for their 449 article.

Also you're probably right about the intended use as a missile controller, the 
limited instruction set shown
would have been adequate for that purpose at the time. I suppose I saw 
'aerospace' and thought such a complex
(for its physical size) machine would have been the preserve of spaceflight 
applications.

Now this has just got me perusing old issues of Datamation  ...some amazing 
forgotten pieces of technology to
be found in there, like the Magnyx 4' x 3' flat panel magnetic non-volatile 
display from 1969. Wow!

Or was it really just a calculator? The mode list in the ad kinda
suggests it wasn't programmable so the human operator may have been
required to be the program and the rest of the "system".

The only source i can see shows that prototypes were shipped to the US

the article you linked, that  it was primarily used for ballistics 
calculations for, say, missiles or mortars. Being what i assume was a

With the technology of the time, I can't imagine it had much memory even

instruction set would help keep the physical size down, but also limit 
it's usefulness in general applications.
I'd suspect it was TTL based, like other (very) late 60's machines, with
