Yes, but you fail to say how ... you cannot use Get Info to get the System version. There is a small freeware app called SysVersion just for this purpose on the early systems that did not otherwise have a way to report it, which may or may not be able to locate the MGT .85 version since it is kept in a different resource than .97 and up. The other way to do it is with ResEdit and look at the original resource code where it is clearly stated.
As Kallikak correctly states, you have to break into the MGT System in order to run such applications on it, as it has been copy protected by Apple specifically to keep people from accidentally using it as a standalone system.
