It seems that the only way you can purchase the James Donnelly book is through
the mail. But, I would really like to know what's in it before I buy it.
Is it just an elaboration on the instruction set, or does it go into other
details of the calculator as well. For instance, did you know that if you
use the [+/-] function on a GROB it inverts every pixel! I didn't, and it
doesn't seem like it was important enough for HP to put in the manual (at
least not explicitly). Does Donnelly's book contain information like this?
If anyone can shed some light on the subject, it would greatly appreciated.
