[argyllcms] Using Argyll with an old densitometer (non-XYZ)

Dear color pros,

I'd like to use the *mighty* argyll to set up a color pipeline for film
work (Scanning/ Grading/Recording). Our hardware/software is custom build,
so off the shelf commercial packages won't fit.

Did any of you already use an X-Rite 810 colour densitometer, just capable
of reading Neg densities in RGB ?

Or can anyone point me to a book or web source how to convert the X-810
RGB-densities to CIE-XYZ space as needed for CMS. I need the matrix
coefficients or the primaries vectors for the color filters and light
source used in the X-810.

If successful and of interest for this community, I'd be happy to provide
the sources for my filmread solution. But regarding the reduced
functionality of the X-810 compared to the newer devices, I doubt it'll fit
to the general device interface used by argyll.
The good thing about it - used X-810's are availlable and much cheaper than
color spectrometers.

Any help is welcome
