Err... yes, of course.
Actually it should better be...
Code:
EEX         -23 2            02

That was much better later with the black paper.

Is or was blue really such a problem? What about copying handwritten text with blue ink then? There are also lots of books (including HP's own Application Pac manuals) that contain printed listings produced by the HP97 and other printing HP calculators. But I admit I have never tried a photocopy of such output.

Our studies are based on Goggin and Lawrence's experience (Goggin and Lawrence, 1975 a, 1975 b) with a renal "diet-package" for the calculator Hewlett-Packard-65. We developed their ideas to encompass later models of the HP-65 and for application to dietetics in general.

So it was indeed the HP65. But there were not many options at that time. Maybe a TI SR-52. ;-)
