Rémy Gibert, the author of A2osX, a now preemptive multi-tasking OS for the Apple II, announces the release of v0.9.1. Rémy is also looking for contributors.

If you believe you could help, please visit https://github.com/burniouf/A2osX

Announcement:

Kernel 0.9.1 is now preemptive. All you need is a “tick” source, see below for supported hardware. For now, only SBIN/BIN executables are “switcheable”.

Roadmap is as follow:
Check all BIN/SBIN sources to make them preemptive compliant, most of them are NOT.
Add a way to make LIB also interruptible and reentrant.
Add more supported hardware for system clock.
…and still hoping finding few contributors…. :-(
