Sorry for the delay in posting a summary, it has been chaos.

The answer was to let the SS 1+ boot thru the self-tests to the boot prom
prompt (i.e. after "ceyloning") and then connecting the 13W3 video cable
from the 17" monitor to the back of the pizza box. All is fine
until the next reboot! And yes, the 17" monitor should work with the old
GX card because the documentation says it can operate at 66Hz or 76Hz.
