HP Voyager
calculator series by Hewlett-Packard
The Hewlett-Packard Voyager series of calculators were introduced by Hewlett-Packard in 1981. All members of this series are programmable, use Reverse Polish Notation, and feature continuous memory. Nearly identical in appearance, each model provided different capabilities and was aimed at different user markets.
Models
The Voyager series of HP calculators included five models, some of which were manufactured in multiple variants (with years of production):
HP-10C – basic scientific calculator (1982–1984)
HP-11C – mid-range scientific calculator (1981–1989)
HP-12C – business/financial calculator (1981–present)
HP-15C – advanced scientific calculator (1982–1989, 2011, 2023–present)
HP-16C – computer programmer's calculator (1982–1989)
HP-10C
The HP-10C is the last and lowest-featured calculator in this line to have been introduced, even though its number would suggest an earlier origin. The 10C was a basic scientific programmable calculator. While a useful general purpose RPN calculator, the HP-11C offered twice as much for only a slight increase in price. Designed to be an introductory calculator, it was still costly compared to the competition, and many looking at an HP would just step up to the better HP-11C. Poor sales led to a very short market life, making it one of the most difficult of the series to find today.
HP-11C
The HP-11C is a mid-range scientific programmable calculator.
HP-12C
The HP-12C is a popular financial calculator. It was such a successful model that Hewlett-Packard redesigned it from scratch, added several new functions, and reintroduced it as the HP 12c Platinum in 2003, along with the HP 12c Prestige.

Why this record matters
The phrase “calculator series by Hewlett-Packard” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 29, 2026. The linked authority identifier is Q846614. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1981, 1982, 1984 and 1989.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
