The history of software is littered with developers that built a great product, gave people a reasonable option to license the software, and ended up making a pittance. There’s a reason you don’t see shareware these days – nobody pays. It looks like [Gates] had a point with his Open Letter to Hobbyists.
Such is the case with Atanua. [Jari] built a nice little graphical logic simulator that has tens of thousands of downloads, and is being used in dozens of universities. [Jari] has sold only about 60 licenses for Atanua, netting him only a few thousand Euro. You can’t develop software with a pittance, so now [Jari] is giving Atanua away. This neat little logic simulator has reached the end of its life, the license is fr*e, and [Jari] is out of the business.
This isn’t an ideal situation, but [Jari] is strongly considering open-sourcing Atanua. The code is a little bit of a mess at the moment, and cleaning it up will require a bit of work. [Jari] is leaving the option to buy a license for Atanua open, and anyone who wants to see this bit of software open sourced could buy a license or hundred.
While this isn’t great news for [Jari], if you’re looking for a neat tool to learn digital logic, you now have a very nice fr*e option. Atanua simulates individual logic gates, 74-series chips, and even an 8051 microcontroller in real-time (up to about 1 kHz), with enough buttons, LEDs, and displays to do some very cool stuff. It’s more than enough to learn digital logic on, and good enough for a test bed for some odd and bizarre projects you might have floating around your head.

Svi kojima engleski nije jača strana, trk na Google translate. Program je dobar i imam dojam da je lakše raditi u njemu nego u Logisimu, bar meni.
