RIP. I was working at the Ascension Island Apollo tracking station during that mission (I worked for the tracking station contractor, Bendix Field Engineering). Ascension Island, along with the tracking station in Spain, were the two tracking stations that tracked the Eagle to the moon landing.

I worked in PCM Telemetry (PCM Telemetry Processor - a special purpose computer) on the tracking station. For the old timers, the PCM Processor had a 4K "core memory".
