Features
Introduced in 1981, the HP 11C was the first HP Voyager model released to the market. The HP 11C is placed between the HP 10C and HP 15C in terms of features offered.[1] Consequently, a large portion of the units manufactured use the earliest Voyager internal designs, as after the introduction of the HP 15C in 1982 popularity of the 11C fell sharply.[2]
