Heh, correct, OS-9 is not Linux. It's similar to Unix (sixth or
seventh "edition") in a few ways, but unlike it in a number of other
ways. If you program in C, though, the two systems are similar enough
that many programs for one can be compiled and run on the other.

As such, with careful programming, you can compile an OS-9 C compiler
(which was itself written in C) on modern Linux/Mac/Windows systems
and expect it to produce working 6809 assembly code from C input. Many
programmers are not sufficiently careful to make this happen fully,
but in this case got within shouting distance of it.
