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).
