If I remember correctly the octopus was actually in a Rate training manual for third class Petty Officer..Few years later the Navy was purchasing a signal tracer, octopus in a box with CRT.


Few years after that we were tracing circuit cards,(mapping the circuits) on known good working CCA's ( circuit card assemblies) saving them to floppy disk ( showing my age here) and calling them gold disks.

Then we could compare the gold disk to a suspected bad CCA and trouble shoot using the circuit tracer.


Sort of taking the TECH out of technician and using computers to compare results.

This system was called acronym,,,ATS or Automated Test system, big huge Texas instrument main frame.


The 2M microminature repair techs ( interpret as solder techs) said the new system was just throwing parts at the problem and the technicians forgot how to trouble shoot, were only changing the components the computer program suggested and not verifying the componenet was actually bad.
