> The 8650 is all ECL, man. We're talking really fast gates here... The 8650 was pretty slow for an ECL machine, as I think it was just 10K. That really is not a big step above something using 74ASxx series technology. 100K, MECL III, 10G and 10E were the fast ECLs. William Donzelli aw288 at osfn.org
