ECL, if done properly, uses a terminator on every signal line.  On MECL it is usually it's 560 ohms to -5.2v or 220 ohms to -2.2 volts. Because most circuits have two ouputs, signal and not signal, termination gives you almost a steady load.  This termination and balanced lines gave the Cybers very fast signal propagation with little noise like Will mentions.  And it requres a lot less regulation and filtering requiremets for the power supplies.

It was a joy to design with ECL, if you ignored the horrendous power required.  We could weld with the Cyber power supplies!  And if the freon cooling failed, you got some interesting smoke within seconds.
