V2_OS
Dutch origin. V2_Lab at Rotterdam. X86-System written
completely in Assembler. Only 37K big. Modular system.
Now sources available.
Vino (Harvard
University)
VINO's key attributes are reusability of kernel
mechanisms by user-level applications,
application-directed kernel policy, and an access-method
paradigm similar to that used by database management
systems. The goal of VINO is to reduce the size of
conventional operating systems by leaving the definition
of complex kernel policies with applications.
Additionally, the VINO system will provide improved
performance for applications, since they can retain more
control over their resources. Finally, VINO is designed
to enable the development of new applications, such as
real-time video, that require explicit control of system
resources.

VSTa
VSTa is an experimental kernel which attempts to blend
the design of a micro-kernel with the system organization
of Plan 9. The result is a small privileged kernel
running user-mode tasks to provide system services such
as device drivers, file systems, and name registry. Like
Plan 9, each service provides a file system-like
interface.
VxWorks (Wind River
Systems)
VxWorks(R) is the premier development and execution
environment for complex real-time and embedded
applications on a wide variety of target processors.
Three highly integrated components are included with
VxWorks: a high performance scalable real-time operating
system which executes on a target processor; a set of
powerful cross-development tools which are used on a host
development system; and a full range of communications
software options such as Ethernet or serial line for the
target connection to the host.
