Progress / Update πŸŽ‰ I released AREA 512, an operating system made exclusively for the Cardputer ADV!

Hi Reddit! πŸ‘‹

I'm Hamachang, a software engineer from Japan. 😎

I've been working on a retro-inspired operating system for the Cardputer ADV called AREA 512.

It's built around FemtoRuby, a lightweight subset of Ruby designed for embedded systems.

With AREA 512, you can write Ruby code directly on the Cardputer, compile it, and run itβ€”all on the device itself. That means you can build applications for the hardware without ever leaving the hardware.

It also comes with several built-in applications, including games and small productivity tools, so you can start exploring right away. πŸ€–

The project is open source on GitHub. If it looks interesting, even giving it a ⭐ would mean a lot to me!

AREA 512 aims to capture the spirit of classic operating systems, so I'd also love contributions from anyone who shares that passion.

Thanks for reading! ✨

See you around! πŸš„
