In the RDS publication is a file called NSRLOS.txt which lists the operating systems on which all the applications in NSRL claim to run. It is a list of the strings one finds on the materials (side of a box, in a manual, etc.) as a prequisite for using the application.
We do not (yet) have all of the operating system products listed in NSRLOS.txt, but I do not think that was your original question. NSRL has in hand the operating systems listed as such in NSRLProd.txt.
Questions? Please contact the NSRL at firstname.lastname@example.org.
