Bell & Howell Apple II update

Actually, back in the Apple][ days, the BNC was not commonly used for video
and particularly not for NTSC video. The most common connector for video back
then was the PL259 (?), which was really common on "security" monitors and
others of that ilk. I've still got a few of them from back then, and that's
what they had on them. It wasn't uncommon to see them with two of the things
for chaining them, though that probably wasn't common on monitors for the home
computer market.
