HP 15C 'Collectors Edition'
I haven't posted a calculator for a long time ... for those that aren't aware, i've got a museum that showcases the evolution of this technology from the slide rule days to now. This includes HP prototypes and some rare items. I've got a display case in my office that houses the most interesting ones.
The Hewlett Packard 15C was the most powerful of the Voyager series of HP calculators. It was originally produced between 1982 and 1989. It was highly capable for such a small machine, programmable with numeric integration, root solver, matrices and complex maths.
Whilst its financial sibling, the 12C, has remained in continuous production since 1981, the 15C was dropped in favour of the Pioneer series of calculators in 1989.
There was a strong push for HP to re-release the 15C (which could share the same casing and processor as the modern 12C). HP eventually produced a 'Limited Edition' re-release of the 15C in 2011. I thought this would be the last incarnation of the 15C, but no ... the 'Collector's Edition' was released last year (2023). Some subtle differences such as no "Hewlett Packard" writing along the bottom line below they 'f' and 'g' keys. But it's got an amazingly fast processor that would put an original 15C to shame on a complex calculation.
