Can't see anything wrong with an 11C saying 0,000 .
Or do you mean you want a decimal point instead of the comma?
If yes, turn the 11C off, press and hold the decimal point key,
press the ON key, release both.

Here is a scanned copy of the HP-11C Owner's Guide from HP's website.

Hi,
After asking the same question on this forum a while back, I wasn't satisfied with the answers that I have received and made my own reasearch about his situation with the HP 11Cs.
According to "A Guide to HP Handheld Calculators and Computers" by W.A.C. Mier-Jedrzejowicz, 5th Edition there has been some early HP 11Cs produced without the "*" sign on the screen.
Some may tell you that early Voyager series may fail to detect the low battery voltage and maybe you should also take this into consideration, however, the HP 11C that I have do not have a "*" on the LCD.
Hope it helps,
Onur
