Darn it, you beat me to the punch!
Some people have mentioned an early version of RTEMS (the Ada version of
RTEMS is deceased now I think) and one called "PULSE" I think. A colleague
at a company I worked at told me that he had written an OS kernel in Ada 83
while in graduate school without much trouble.
It all depends on what one means by OS. If one means a complete Unix
clone, then no, I don't think one has been written in Ada, and it would be
silly to do so since Unix users expect C APIs. OTOH, a complete new OS
functionally similar to Unix/NT/VMS/AS4000/... in Ada would be an
interesting research project. It can obviously be done, since Ada-95
provides all of the capabilities of C, and much more. So, like Dale, I
have no idea what kind of point "Dr Amirez" is trying to make.
