My perception is there has been a steady stream of analog circuit work in recent decades (not quite pure "analog computing", but related to it) due to the integration of analog signaling into cell phone chips that otherwise are digital (see https://en.wikipedia.org/wiki/Mixed-signal_integrated_circuit https://en.wikipedia.org/wiki/Mixed-signal_integrated_circui... ); not sure if any of that is relevant to your explorations.
