Unfortunately I cannot help you with a manual. To change the decimal point press "f" followed by "FIX" (above "7") followed by "5" (or any number from 0 to 9 depending on the number of digits desired. Similar for SCI and ENG modes).
By the way, there is a more active forum for current HP calculators here:
Also an active forum for users and collectors of older HP calculators:
Hope this helps

as a novice according to the hp 11c I need the help of an expert: I worked through the owner's handbook thankfully downloadable from HP-Company (http://h10032.www1.hp.com/ctg/Manual/c00503576.pdf). Obviously a successor, the HP Solutions Handbook, was available in 1985, but it seems to be invisible in the www except some e...-auctions and a cd-version (www.hpmuseum.org). Are you familiar with this solution handbook and do you consider it as a must have for the engaged user? Is there a download from HP that I was unable to find? I like the calculator very much and hope to find inspiration in that solutions handbook but maybe it is only a collection of well known concept like simpson's rule, matrix inversion and so on.

I have an original HP-11C Owner's Handbook and Problem Solving Guide, May 1984.
It does include specific methods for running lengthy programs like Matrix inversion (pg 210-211).
I would say the manual gives specific use tips that help in how to get more calculating power with limited memory.
Anyway....asking $15 plus postage.

The 11C manual is currently available on the HP website:

The decimal point has changed from a decimal point to a comma and I don't know how to change this back to a decimal point. Can you help me?

Switch the calculator off, then press and hold the decimal "." key and simultaneously switch the calculator on.

Thank you very much for your last helpful comment on turning the comma back to a decimal. However, the RAD sign is appearing. How can I get rid of this? Also, is there a user manual anywhere I can download?
