Maybe my question wasn't precise enough. In fact my question is: Is it
correct to assume that there is always a 64k /RAM device at the point
of time when GS/OS booted into ProDOS 8?

I don't have access to the GS/OS reference.

Yes, that's just the SYS file.

I don't have access to a running GS/OS installation. Could you please
elaborate on this? Especially on my question above. Has associating of
data files something to do with file types, file name schemes or is it
a file-by-file approach - as I understand from your remark above?

Best, Oliver
