Historical and adjusted-for-inflation prices of calculators

[John Ioannidis]

I've been wondering for a long time how (un)realistic prices on The Auction Site are for some of the rarer models — an HP-19C in excellent condition goes for amost USD 1K.

I chose as my cut-off point the year the HP28C was introduced. With its weird form factor and language, it no longer counted as an HP calculator for me.

The prices are prices at introduction of the base model.

The CPI data are from the Bureau of Labor Statistics: https://data.bls.gov/timeseries/CUUR0000SA0

While we are at it: there were two versions of the 32SII, the one with the traditional color scheme, and another (a re-implementation?) with the idiotic low-contrast HP-48G-like scheme. The museum does not have a picture of the latter, nor years of introduction or prices.

IMnsHO, the only decent calculator introduced in the last thirty years has been the HP-35S. Proper, high-contrast keyboard, excellent tactile feedback. Between that, and the excellent HP41 emulator for the Android (go41CX), all my calculator needs are handled!
