50/60's era US Sonar Systems?

Howdy,

One mystery Ive always had is the look of US 50/60s era sonar. I have no good sources.

When did the waterfal displays start...Was this something developed in time for Skipjacks, or was this Sturgeon and later?

When was HF available?
What about narrowband identification and DEMON systems?

What kinds of sonar were available on Guppy, Nautilus, Triton, or Skate type boats?

Mainly curious for personal interest, but also wondering how far off 688i interfaces are if I use SCX to play Skipjack.
