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.
