Yes, I agree. It is simply awesome. Thanks a lot! Bests, Jordi PD: I also love old calculators, though my first love was the HP-41CV

Sven. This is outstanding.

It is not only a comprehensive tutorial, but also is good loking, with a little touch of nostalgia for those who used a RPN calculator in the past :)

I wish we all could produce code and documentation the way you do. Maybe cloning you is an option.

Congratulations.

Best regards,

ps: there is a typo in the first image of "Modelling the HP-35" section.

Hi,

I have written a new, extensive, long form, introductory article about Pharo.

Rediscovering the UX of the legendary HP-35 Scientific Pocket Calculator

A tutorial on Pharo, test and specification based immersive programming

https://medium.com/@svenvc/rediscovering-the-ux-of-the-legendary-hp-35-scien...

It is a bit different because

- it is based on a non-trivial example - it uses a backdrop story unrelated to Pharo - it uses several multimedia elements - it is published on medium.com which is a general publishing platform

The appendix describes several ways you can get the code. I think building both a Spec and Seaside UI from the same specification as well as reusing functional tests in different contexts is cool. Anyway, I hope you enjoy it.

Sven
