The overall discussion is very useful, but in my particular case, it needs
to pertain specifically to the IBM 650, because the assertion at hand is
that a document used to discredit a certain scientist's claim to a certain

650 using its internal clock feature. The 650 does not have such a
feature inherently, so now I'm trying to determine if there was ever an
adjunct product that IBM produced to give the 650 the ability to tell
