It's working guys. Thanks a lot for all of your help.
In the interest of public information:
The BNC connectors do, indeed, carry composite video.
These (at least the model I have) contain a "kill switch" in the little add-on
that's bolted to the back of the machine. In order to get power to the internal power
supply, you must have the switch depressed -- or the "cover lock" bolt in the
locked position.
Thanks again guys.
Err -- anybody know a good way to run some diagnostics on the machine? :)

Can THIS finally put to rest the assertion that BNCs were not used for
video??

Well, the Sol-20 for one used that type of connector as a stock component.
I can't think off-hand of any others that used that type.

Just in the interest of sanity, how many used the fatter
screw-on UHF type?

Well, how about pointing to one for starters? I don't think I ever saw a
video board for the S-100 that had any sort of cable termination on the distal
end of their cable, if there was one, except, perhaps, for an RCA jack.
The machines I owned that used something other than a dedicated monitor of
which the Vector Graphics cheapie I owned for a short time is an example,
generally used a serial terminal. While there were several other ways of
handling the console construct, or, for that matter, the graphics display, if
you wanted one, they generally were on boards that more or less required you
to make the choice of connector, however, since the board was generally
shipped separately from the box. If you went to the computer shop, you would
definitely see cables with PL-259's at one or both ends. Of course, you could
buy an adapter that went from SO-259 to BNC. I don't remember there being
RCA<=>BNC cables at these computer commodity stores, though I'm sure they
existed.

Please, Richard. I probably should've asked the

I am pointing to my nose. The outermost joint of my index finger
is touching my closed mouth. My wrist is below chin level. I am
making a sound. etc. etc. etc.
The sound is Shhhhh.

both were used, it just depended on who made the monitor.

Now that that has been put to rest, didn't the Wang PC have a BNC video
connector, ISTR that my peripheral-orphaned one, which was abandoned 2
moves ago had one.

If it's a //e, hold down the closed (solid) Apple key and press Ctrl-Reset.
(If you see a screen that alternates between solid white and black, you have
an unenhanced //e with 64K of memory. If you see a screen with random large
colored pixels, you have an enhanced //e with 128K of memory.)
If it's a ][ or ][+, find a diagnostic program on disk -- there are no
built-in diagnostics.
If things are mostly working, you could use BASIC to do some simple
diagnostics (test the keyboard, game paddles, graphics, etc.)

Yes, they do. In fact, I just saw one carrying DC power. It was part of an
adapter at the other side of which were two banana plugs. Don't ask me why.
