Code:

LBL 2     21 02
RCL (i)   36 45
f FRAC    16 44
1            00

Of course that should rather be:

Code:

1            01

Quote:Why didn't they simply attach a printed program listing?

You could ask Prof. Dr. David H. Shmerling. He's still listed as Titularprofessor für Kinderheilkunde in the Children Hospital in Zurich.

I remember that the colour of the thermal paper initially was a blue that was hard to photocopy.
That was much better later with the black paper.

Quote:Then take a look at the references. There are two papers that sound very interesting: Goggin, M. S., Lawrence, D.: "Dietary calculation by pocket-size computer" and "Pocket-sized solution to the dietitian's workload", both published in 1975. Could these possibly refer to the HP65 ?

Cf. page 268:

Quote: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.
