Thank you very much for the reference to RTEMS. I downloaded version 4
only to find out that the source files are in C. I keep reading on
several sites that there is a version of RTEMS written in Ada; however,
I can't find it.

It is my understanding that I can compile Ada source into object files
with GNAT and link them with RTEMS which is written in C to run my
applications on lets say an M68K. Because of the nature of the project
I'm working on - master's thesis - I'd really like to be working with
code from the same language - hence my desire to find the Ada version of
RTEMS.
