Let me know if you want me to dig it out. Just pay shipping.

Unfortunately, no. You've got to have an Apple ADB keyboard to see
that (enter the NVRAM setup screens by hitting Ctrl-OpenApple-Escape,
and select the 'RAM Disk' to do so).

cable work?
A straight-thru S-video cable will work just fine.

Does the converse work? Can I use ADB cables for
S-Video?

I cna't believe either the characteristic impedance
or the construction
is the same between ADB and S-video cables. Electrically the connections
should be the same, but if you use a ADB cable for S-video, you might
well get noticeable reflections.
IIRC, S-video has 2 ground pins on the connector, and there's nothing to
stop them being commoned in the cable. Would that cuase a problem if
sucha a cable was used for ADB?
See http://www.applefritter.com/node/9214 :
"Both ADB and S-Video cables use 4 pins, and are interchangeable.
Keep in mind that some S-Video cables are of higher quality than
ADB cables, so if you use an ADB cable for S-Video, the signal
may not be as good as if you used a proper S-Video cable."
"The only difference between an ADB cable and an SVideo cable is that
the ground pin and the shell are connected together on the ADB cable,
and the ground pin on an SVIDEO cable is not connected to the shell.
The only problem this causes is some devices don't detect the cable
being plugged in and won't switch to it."

I have no idea. I have never used S-video cables for
ADB, I always went the other way around (because I
have tons of ADB cables...) If you compare the
pinouts, and assume that the grounds of an S-video
cable were connected together, then the data line and
the power switch sense line of the ADB bus would be
connected together. No idea if it would work like
that, but what would happen when you hit the power
switch? Is that signal active low or active high?

I've never had any trouble using an ADB cable as an s-video cable. I've
never tried it the other way around though.... ADB cables are a lot
more cheaper and more plentiful than s-video cables...
