 A simple operating system for the **Clockwork PicoCalc**, written in Rust.  
 This project provides a minimal kernel, ABI, and user-space applications to experiment with OS development on constrained hardware.
 
+## Status
+
+Basic synchronous applications are working great.  
+Current focus is on **expanding the ABI syscalls** and **fixing the MSC/USB-SCSI driver** to make application development easier and smoother.
