Greg, are you sure the 11-780 was ECL? I vaguely thought it was TTL. Certainly the 11-750 a year or two later was TTL. 8700 was ECL but that came much later.
Yep, The 11/780 was TTL the MicroVAX was NMOS and the sucessors were CMOS with the top-line servers being ECL. See : http://simh.trailing-edge.com/vax.html
