Hi Bill,
Screens, and the like (projectors etc), use a different color theory from pigments such as paint. One is additive color theory, the other is subtractive. You will be hard pressed to find a match between the two. 

I’ll forward you and Al a photo showing the 7690 pantone chip places on my IMSAI case as a side by side comparison. Color-wise, it’s almost a perfect match.
