You have the latest version. 1-1/72 is the newest version available for the MKI system, and it has not changed since the V17 OS distribution disk. That is why the V27 disk does not load-- it has the same MKI software as the V28 disk. You would have to go back to the V16 disk or earlier to load something different on the MKI.
