    SGI kit can be fiddly when it comes to the video cables and
connectors you use -- specifically, if the correct monitor select
bits aren't present on the 13W3 connector you'll wind up with a
blank screen.  Check to make sure you have the correct adaptor
cable if you're using a PC monitor.  (If need be, I'll Ohm out
a adaptor I have (from an old projector) and pass the pin notes

    It's possible to boot most SGI gear "headless" (I do this with
an Indy that I use as a stereo component) but you need to get the
setting into the NVRAM to use the serial port instead of the video
port and keyboard.  In this case, I suspect you're in a catch-22
situation; I could not boot my Indy without the keybaord attached,
and it'd never try the serial port until I connected video and
keyboard, made the required changes, and rebooted (it also reports
as a "Challenge S" in this configuration).
