Actually, the product you refer to is known as OS-9000. OS-9 was written in
assembly language for the 680x0 and 683xx families; we re-coded the kernel
and file managers in C so that we can more easily port OS-9000 to other
platforms, which today include 68020/30 and 80386SX/386/486, and will include
RISC implementations later this year. Of course, certain critical parts of
the kernel still need to be done in assembly language of the host processor.

Thanks for the plug!
