They do exist. Well, sort of - not much _micro_ about them :-) - a PDP11-04 main processor was entirely bipolar logic - the board is about 30x20cm - I've got a couple somewhere. IBM introduced CMOS-processors in their ES9000 range around 1991 - prior to that they were all bipolar ECL and watercooled. /Per Jessen -- http://www.spamchek.com/freetrial - sign up for your 30-day free trial! _______________________________________________ Prime mailing list [email protected] http://hogranch.com/mailman/listinfo/prime
