Octane's are awesome.
Octane's that run are even better.

Here is one possibility
The machine is set to boot from graphics and you are trying to connect
to a non-13w3 monitor using a Sun (or one labeled Sun/SGI/DEC)
The coaxial bits of the 13w3 connector (the w3 part) are reasonably
standard across vendors. The stuff in the middle (the 13 part) is not.
So, if your adapter works with Suns it likely won't work with an SGI.
I've found that many monitors are confused if, say, they are recieving
H sync on one of the Monitor ID pins.
A quick fix to the above problem, assuming you are sure that your
monitor supports Sync on Green and you are willing to commit an adapter
to this purpose, is to snap off the 13 pins in the middle. This will
only provide R,G and B to the monitor. Irix may report the monitor as
"unknown", but this shouldn't affect anything and you should be able to
see the machine POST.
Also, double check you have the keyboard connected to the right port, I
believe it is the one closest to the inside. There are little icons.
To my embarrassment, I wasted over an hour wondering no keyboards would
work on my Octane when they were connected to the mouse port...

This is good. POST was finished and it should be booting whatever OS is
on the system (hopefully IRIX).
As a last resort, I'd try to reseat the graphics card. Do be careful.
Read the owner's manual for all of the caveats about compression
connectors if you haven't already.
