There was the Chromega Subtractive Color Calculator, and Beseler had a
similar product. You occasionally see them on Ebay, and some of the
second-hand photo sites.
I did a quick search for "chromega" and "calculator" and found the
following site as an example:

There are a number of different calculators listed.

Beseler still lists a calculator in their current catalog:

Unicolor also had one called a Unicube.
I taught color printing schools for Beseler. Those calculators worked quite
well PROVIDING that you understand the basic concept. You made an exposure of
the calculator through a diffuser onto a piece of color paper. Then you
selected the color filter square that most closely resembled neutral gray. It
worked well as long as you selected a negative that had an equal amount of the
primary colors that would diffuse to neutral gray. Those in the know would
expose a Kodak gray card on the first frame of the roll and use that "control
negative" with the color calculator. As long as the color of the light and the
emulsion of the film and paper did not change that filter data would be a very
accurate starting point for the rest of the negatives on that and other rolls.

The various cubes which are available provide a starting point
for exposures. Essentially you look for the greyest spot, and
this helps you set the exposure and filter setting.
What you might want to consider is the Kodak color print viewing
filter kit, which provides a number of filters through which you
can view an exposed and developed print to decide how to adjust the
exposure.

mention. I was just wondering - would it work to swing the diffuser in front
of the lens when using the print-cube calculator? When using the analyzer, I
will sometimes (when I don't have a skin tone, white or gray to base the
exposure on) swing the diffuser under the lens and use a gray calibration on
the analyzer. This works very well. ------ Jerry/Idaho

Jerry,
That's exactly what you do, swing the diffuser into the light path when using
the cube calculator. You then find the square in the grid on the print that is
the closest to middle gray with no color bias and use the filter combination
that composes that grid square. It works best if the negative has a fairly
equal mix of color and is an "average scene" (whatever that is). Or, as I said
in my previous post you can use a gray card to shoot a test negative and use
that negative. Make sure that you fill the negative space with the gray card
so it diffuses to middle gray onto the cube.
I own both a color analyzer, Beseler PM2, and the grid calculator. I also used
the grid and certain negatives that I knew worked well with it to quickly get a
good print from a new emulsion batch of paper to calibrate the color analyzer.

Bob Mitchell was a good guy, I had the chance to talk with him shortly
after Omega Satter took over the Colorstar product line. He was really helpful
to me despite his obvious dismay at Jobo having forgone the productline.

sense of humor. He has many photographic inventions to his credit. I
have bought and used several that were sold by Heathkit. Two that
seemed like great ideas - canoe and color analyzer, just did not sell
well. He was the first one to make jokes of these two. One of his last
invention, Hocus Focus, a focusing aid is ingenious and quite good.
