The HP-10B (F1636A) is a student
business calculator introduced in 1987. The model of this calculator proved to compete well with the higher end
RPN HP-12C

Two versions of the 10B were produced, the first version came with orange lettering around the keys and used an 1LU7
HP Saturn
The Saturn family of 4-bit ( datapath) microprocessors was developed by Hewlett-Packard in the 1980s first for the HP-71B handheld computer and then later for various HP calculators (starting with the HP-18C). It succeeded the ''Nut'' family ...
processor, the later model (in 2000) with teal-green labels. The functionality of the two versions appears to be identical.
The successor HP 10bII (F1902A), which was introduced in 2001, is essentially a cosmetic upgrade offering the same overall functionality, but actually reduces the available numbered-storage registers from 15 to 10. Early production runs were of poor quality; newer calculators have apparently solved this shortcoming.
In 2011, the 10bII was replaced by the HP 10bII+ (NW239AA) model 1 (codenamed "Bluestar") with expanded capabilities. This model also allows
chain input
There are various ways in which calculators interpret keystrokes. These can be categorized into two main types:
* On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate resul ...

The part number and physical appearance of model 2 didn't change except for a "Rev 2" plate on the bottom side.
The serial numbers of the new model start with "PHA".
The 2×3-pin flash port now uses the USB protocol instead of a TTL serial protocol.
None of the five models supports
RPN.
