Some of the biggest monsters of that era weighed well north of 20 pounds. My back starts to ache when I merely think about the effort required to erect one. Also got a kick out of the text in that book describing the difficulty of capturing signals strong enough to render a good color picture. Sounds rather familiar, doesn't it? We're back to the future, alright!
Thanks for that, EV. I vote for uploading a few good readable examples.
