View source for 500-series plug-ins (Letter-series and 1-series)

These '''plug-ins use the [[500 Series plug-in interface|500-series plug-in interface]] and fit in [[500-series scopes]]''' as well as external power supply units such as the [[127]], [[132]], and [[133]].
 
The transition from letter-series plug-ins to 1-series happened in fall of 1965.
