VAX9000 built of ECL100K, fastest of the fast. The
second most common
use of TTL was in very high speed instrumentation and specifically frequency
counters and UHF PLLs.
If the 9000 series was till using 100K, DEC must have been sleeping.
By the 9000s development period, ECL was beyond 100K. I am not sure,
but 10E may have been out by then. 10G maybe as well, but using that
leads to insanity.
But one thing I notice about DEC's ECL machines (9000, KL10) - for
being ECL, there sure were ssssllloooowwwww.
