I think it's mostly a matter of testing for the precense of features,
e.g.:

        cache   extended
2040    no      no
2050    yes     maybe
2060    yes     yes
2065    yes     yes

An extended 2050 looks much like a 2060, but maybe the microcode
version was different, or something.  The 2065 had a larger microcode
store, so again maybe check the microcode version.

alt.sys.pdp10 may be a source of information on exact machine
identification.
