start [HP Calculator Wiki]
This wiki was originally created to be a development home for repurposing the HP-20b calculator, but has since grown to support several repurposing projects. It is our hope that this grass-roots approach to calculator hacking will expand to include other many HP calculator models and open-source projects.Mon Nov 19 13:56:45 2018 - permalink -- http://www.wiki4hp.com/doku.php?id=start

A Hewlett Packard Infrared Signal DecoderThu Feb 15 11:07:58 2018 - permalink -
Martin Hepperle
June 2015
Several Hewlett Packard pocket calculators are able to send printer output via Infra-Red (IR) signals to a small portable printer. They use an HP-specific transmission protocol which is also called “Red Eye”. This protocol is different from the better known IrDA protocol. This document gives a brief overview of the format and describes hard- and software to build a decoder system for this protocol.
This system allows receiving the “Red Eye” signals with a computer via a serial or an USB interface.- http://www.mh-aerotools.de/hp/red-eye/HP-IR%20Receiver%20with%20Arduino.pdf
