New HP calculator literature site

Why do we need these feats with manuals? Any normal user will find the information he needs in any resource. I recently ran into the problem that no other calculators except hp-50g can not save different objects in the list when entering information on a program request. I no longer have any desire to share information in the manuals. Perhaps age and personal experience affect. The one who does not know is the one who speaks. The one who knows a lot - he is silent. :-)
