Karl, what a shameless lie! We hung just under 30 miles of UTP (plus several more of fibre), you must have fallen asleep at dawn Sunday. The number of drops was not uncountable (wish I had an aleph character here), it was a finite integer, less than a zillion. >One thing that made life much better for the '90 Interop over the '89 show >was that we found some real nice RJ45 crimp-ons for building the cables. >(These were from Thomas and Betts.)

I guess we shouldn't mention our "is this RJ11 or RJ45" dance of last year. Seriously folks, running ether over utp was bliss this year, I should have paid more attention to the miniscule portion of the net where token-ring was run over utp, perhaps someone who took a look at that portion of the net could drop me a line. #include Eric Brunner, Consultant, IBM AWD Palo Alto (415) 855-4486 inet: brunner@monet.berkeley.edu uucp: uunet!ibmsupt!brunner trying to understand multiprocessing is like having bees live inside your head.
