VSTa

VSTa (Valencia's Simple Tasker) was an operating system with a microkernel architecture, with all device drivers and file systems residing in userspace mode. It is mostly POSIX compliant, except when POSIX compatibility got in the way of extensibility and modularity. It was conceptually inspired by QNX and Plan 9. Written by Andy Valencia, and released under the GPL license. Currently the licensing for VSTa is Copyleft.

VSTa was originally written to run on Intel 80386 hardware, but was subsequently ported to several different platforms, e.g. Motorola 68030 based Amigas.

VSTa is no longer developed, a fork called Flexible Microkernel Infrastructure/Operating System (FMI/OS) did not make a release.[1]

User interface

The default graphical user interface provided as a tar-ball with the system was ManaGeR (MGR).
