HP-10B

HP 10B, first version

The HP-10B (F1636A) is a student business calculator introduced in 1988. The model of this calculator proved to compete well with the higher end RPN HP-12C.

The later-model 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 suffered from poor quality; newer calculators have apparently solved this shortcoming.

Two versions of the 10B were produced, one with green lettering around the keys, one with orange. The functionality of the two versions appears to be identical.

In 2011, the 10bII was replaced by the HP 10bII+ (NW239AA) model with expanded capabilities. This model also allows chain input. The 10bII+ uses a flashable Atmel AT91SAM7L128^{[1][2][3][4][5]} processor with ARM7TDMI core.

None of the three models supports RPN.
