    I am looking for records related to NASA's Saturn V telemetry system. Specifically, I want to find out if the telemetry used an SNX1304 to optically isolate the PCM/DDAS system and the internal circuitry of the computer interface unit (CIU).


      The SNX1304 was an Optoelectronic Pulse Amplifier released to market by Texas Instruments in March 1965.


      Using an SNX1304 for optical isolation in the telemetry system was an idea proposed by T. C. Lawson of the Marshall Space Flight Center in a May 1966 paper titled "Integrated Circuits In Telemetry Systems".


      It can be found on pages 33-40 of the following document:
