I want to ask a question about using nitros9. Nitros9 is a modern clone of the original OS-9 operating system used on the coco3. Nitros9 is run on both vintage coco3 hardware, and on modern emulators hosted on Windows or Linux.
I'm unsure if the question would be considered on-topic, for these reasons:
nitros9 is still being developed. The most recent build I've found is from 2014, so nitros9 is not itself retro.
nitros9 is largely the same as os9, but I think there are differences. I never ran OS-9, so I don't know if any differences there are would matter for my question.
Possibly applicable meta question
This question is similar to Are legacy OS's on modern systems on-topic?, except that I am asking about a clone of a retro OS on retro or emulated retro hardware; that question is asking about running a legacy OS on modern hardware. The advice given in that question's answer, which seems good to me, is:
A general guideline is to look where the problem asked is originates.
When it's on the 'classic' side a question is perfectly on topic (like when in above configuration a your Assembler produces unlinkable output).
When it's due to some emulation software it might be on topic, as these are tools within the RC scope.
When it's about modern environment/OS or modern non RC specific tools it's clearly off-topic.
The first and third points of that list are salient: If nitros9 operates the same as OS-9 in regards to my question, then my question is on-topic, because it is the classic side of the question that it applies to, according to the first point. If, however, nitros9 operates differently than OS-9 in regards to my question, then my question is probably off-topic according to the third point.
My trouble is, I don't know whether Nitros9 differs from OS-9 in any way that matters.
The gist of the actual question
The question I want to ask is how to abort the EDIT editor without saving the file. The EDIT editor in Nitros9 appears to be the same as that in OS-9, because I am able to use original OS-9 documentation to learn how to use it. However, there may be differences that I am not aware of, since I was never an OS-9 user.
(If I actually do ask the question, it will have more detail).
Should I ask this question?
Would this question based on a modern clone of a retro OS, which may have differences from the retro OS, be on-topic?
