I do love ECL, ever since the 100K family appeared.

Fast, clean supplies, clean impedances, controlled rise/fall times...
Not like that sh***y CMOS on steroids.

Around 1979, I built a  real time signal averager that could
keep up with a TRW 8 bit 20 MHSPS ADC. The ADC was bleeding edge;
we got also a nekkid chip in an epoxy? cube, being a pilot customer.

It took 8 interleaved 74LS/S computation units to do the job;
a few years later I migrated that to a dual ECL implementation
while increasing ADC speed to 200 MHz.

When FPGAs became available we used them as the final solution
because less power burnt meant more miles of oil/gas pipeline
inspected with ultrasonics per run.

3rd picture from top, The blurred part in the background
is the original 74(L)S version; the one board on top replaced
the entire 19" crate with 10 times the speed. The 200 MHz
control machine is still ECL.

Cheers, Gerhard
