Curious mistake in the Voyagers brochures

[borjam]

I just received the Museum flash drive and there was something I recalled from the 80's: A brochure I had in Spanish stated that the HP-10C had the gamma funtion. It does not, though.

And indeed, the blue brochures (Achieve better results, etc) state that the 10C has gamma.

Just amusing.

(Unfortunately I no longer have that brochure although I see it has been scanned in English, Spanish and German at least).

Here we go: HP-10C

Quote:The program fits neatly into the calculator, with the only down side being its slow speed of execution; obtaining a result may take up to two minutes.

Thank you! I know the page.

I just mentioned it because I found it amusing to see this mistake in HP literature. It appears on the "Achieving Better Results" brochures. The error appears on the HP-10C description and the specifications summary (it says it supports Factorial and Gamma).

For the record, I own a HP-10C and indeed it does not support Gamma.

I know:
\(
\begin{array}{|l|c|c|c|}
\hline
\textbf{Statistical} & \textbf{HP-10C} & \textbf{HP-11C} & \textbf{HP-15C} \\\hline
\text{Factorial} & \text{Yes} &\textbf{Yes} & \textbf{Yes} \\\hline
\text{Gamma} & \text{-} & \textbf{Yes} & \textbf{Yes} \\\hline
\end{array}

Thanks Thomas, I never realized (or completely forgot) the 11C had Gamma, though I have more than one of these. I've long thought only the 15C had it among the Voyagers.
