If you are as nerdy as us, you know Forth of course. The tiny language coming with compiler and editor and still not only fitting into the limited memory of 8-bit machines, but leaving plenty of room for user land programs. Forth was developed by Charles H. Chuck Moore and and saw the light of the digital world back in 1970.

Still, believe it or not, Forth is in use. Today! And not only, but also especially in space! Forth actually ran for example on the Philae spacecraft 🛰 and was used to create the Electronic Arts best selling game Starflight.

However, Thanassis Tsiodras decided to give it a spin and built a tiny Forth compiler for the Arduino Uno in one week. His post accompanied by a number of videos is well worth the read.

Enjoy.
