I think the card probably has a lower-case character set, though I can't
be sure.  The Videx card I used had a female RCA cable on a pigtail coming
out the back of the computer.  I had hooked the monitor to that cable, and
got 80-columns.  The trouble was that when the 80-column display came up,
the normal video simply froze, and I had to swap cables.  Finally, I
installed a switch-box.

If you have two connectors on the card, my guess is that it has its own
switch.  I don't know about the switch you speak of, since you obviously
have a different version of the card than I used.  My guess is that one of
the jacks would connect to the normal video out jack, and the other
connects to your monitor.  That way, the card can swap between signals
when it is powered up.

As for the lower-case display, the lower-case ASCII codes begin after the
upper-case ones.  Using the following BASIC command line, you ought to be
able to display both upper and lower-case text--

FOR X=64 TO 127:PRINT CHR$(X);:NEXT
And you should get something like...
ABCDEFGHIJKLMNOPQRSTUVWXYZ/|\~abcdefghijklmnopqrstuvwxyz...
(I'm pretty sure I'm wrong about the characters between the alphabets, but
you get what I mean...)

If you DON'T have a lower-case display, the lower-case portion of the
display above should be "random" symbols, which may be flashing or inverse.
