thanks ray.  i have'nt received a personal attack from you on the net
since i abandoned soc.all.  nice to see you come out of your closet
from time to time to insult readers in the rest of the newsgroups.

that wasn't the topic of discussion.  there was nothing in berger's
article about meeting fcc standards.  the discussion revolved about
digital logic at 40MHz.

yes, i have looked.  multi-layer pcb's, metallic paint, wire mesh,
etc., etc.  real good work.  but it doesn't have one thing to do with
clocking a cpu at 40MHz.

no.  because he didn't state that he was referring to building a cabinet
to hold the sucker.  [ not to discount the pcb design problems, but you
are still going to have a considerable RF signal coming off the board
even with excellent pcb design ]
