HP-10B

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. Two versions of the 10B were produced, the first version came with orange lettering around the keys, the later model (in 2000) with teal-green labels. The functionality of the two versions appears to be identical. In 2011, the 10bII was replaced by the HP 10bII+ (NW239AA) model 1 with expanded capabilities. This model also allows chain input. The 10bII+ uses a flashable Atmel AT91SAM7L128 processor with ARM7TDMI core.
