I am the author of PicoCalc. I had no idea anyone had posted it here on HN, that it had so many points and comments, or that anyone still remembers it. Makes my day :)
I see the mention of a version that can run a full Linux distro, and that's been my dream for ages--something this shape and size, but that i can use like a normal (tiny, slow) computer. Hopefully that moves along, or maybe i need to hack my own together with this milk-v board i have laying around
No, i saw a project using a Pico-size Linux board in the picocalc shell, which is exactly what i want it's just early in development. There are several cheap riscV boards now in the pico form factor that can run a full distro
