TULIP: The Ultimate Intelligent Peripheral for the HP-41 Handheld Calculator
[Andrew Menadue] wrote in to let us know about the TULIP-DevBoard and TULIP-Module being developed on GitHub.
TULIP is short for “The Ultimate Intelligent Peripheral” and it’s an everything expansion board for the HP-41 line of handheld calculators sold by HP from 1979 to 1990. These particular calculators support Reverse Polish notation which seems to be one of those things, like the Dvorak keyboard, where once you get used to it you can never go back.
In doing the research for this article we came across the fan site hpcalc.org which has been online since 1997, although the Way Back Machine can only go back to late 1998. Still, we were impressed. It’s fun that the site still looks very much like it did 28 years ago!
The TULIP4041 is based around the RP2350 microcontroller which you might know as the heart of a Raspberry Pi Pico 2 board. The video below the break is a talk about the present and future of the TULIP project, and the slides are here: TULIP4041 – The Next Chapter.pdf (PDF).
Thanks to [Andrew] for writing in. If you’re interested in hacking the HP-41 check out HP-41C, The Forth Edition and Nonpareil RPN HP-41 Calculator Build.

This is impossibly cute. I'm spooning the dog on the couch, and he reaches out to hold my arm with his paw.
