All calculators used the same hardware, but differ in keyboard and firmware (which can be changed with an upgrade port).

The series consisted of the DM10, DM11, DM12, DM15 and DM16. In 2011, the continued popularity of the Voyager series among users prompted SwissMicros to produce a series of credit-card-sized calculators looking like miniature versions of their HP equivalents and running the original HP firmware in an emulator on a modern calculator hardware.

Official emulators for the 12C and 15C are commercially available from Hewlett-Packard for Android and iOS devices. The long-discontinued HP-15C was re-released in a "Limited Edition" in 2011 that has again been discontinued. The HP-12C and its derivatives remains in widespread use today and is still available from Hewlett-Packard. Also the programming model is not turing complete. ^ Without indirect addressing only the first 20 (0…19) register can be accessed.^ a b Without DSZ/DSE (Decrement and Skip) and ISZ/ISG (Increment and Skip) writing loops is difficult.^ a b c Available via the g TEST n (indirect) function.^ Without GSB (Go Subroutine) / RTN (Return from Subroutine) one cannot write subroutines.^ Without LBL (Label) goto commands can reference only absolute program steps.^ Without BSP (backspace) programs can only be edited by overwriting existing steps.The available programming features differentiate between the various HP Voyager series calculator systems. These keystroke programs, in addition to performing any operation normally available on the keyboard, can also make use of conditional and unconditional branching and looping instructions, allowing programs to perform repetitive operations and make decisions. The HP Voyager series calculator are keystroke programmable, meaning that it can remember and later execute sequences of keystrokes to solve particular problems of interest to the user. Hewlett-Packard retained the numerical analyst William Kahan of UC Berkeley, the architect of the IEEE 754 standard for floating-point arithmetic, to design the numerical algorithms implemented by the calculators. HP has (as of 2015) never made another programmer's calculator, but has incorporated the 16C's functions in later calculator models.
A number of specialized functions are provided to assist the programmer, including left- and right-shifting, masking, and bitwise logical operations. It can display numbers in hexadecimal, decimal, octal and binary, and convert numbers from one base to another. The HP-16C is a computer programmer's calculator, designed to assist in debugging. The HP-11C is a mid-range scientific programmable calculator. Poor sales led to a very short market life, making it one of the most difficult of the series to find today. 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. While a useful general purpose RPN calculator, the HP-11C offered twice as much for only a slight increase in price. The 10C was a basic scientific programmable calculator. The HP-10C is the last and lowest-featured calculator in this line, even though its number would suggest an earlier origin. HP-12C – business/financial calculator (1981–present).The HP calculators Voyager series consisted of five models, some of which were manufactured in several variants (with years of production):
