RTOS

Ivan,

MapuSoft offers products to move applications from one RTOS to another
and to develop applications that can run on multiple operating systems.
This way you can write one application and test it out on many
different RTOS to chose which RTOS works best for you. More information
about MapuSoft's products OS Changer, OS Abstractor and OS PAL can be
found at www.mapusoft.com

Try QNX Neutrino RTOS vers. 6.3 (QNX6.3) ... a 30 days eval version is 
available.  ( http://www.qnx.com )

I'm sure the previous free version (QNX 6.2, free for non-commerc. use)
is still available in the internet.
