    I found a pretty good mod guide for this monitor to make it work with
    a PC, unfortunately I've long since lost the link but I assume it will
    still be out there somewhere... it contained brilliant step by step
    photographs too. Only problem I encountered was that it required a
    fully connected SGI cable (which I didn't have), so I had to pull the
    signals from another point on the circuit board and used a couple of
    the unconnected pins in my cable. The results were usable, but the
    picture was shifted over to the left so you had to adjust the screen
    settings on the monitor, also the max resolution I could get out of a
    PC with this monitor was 1024x768, and had a darkish tinge but wasn't
    too bad really. That particular monitor has been in use up until
    about two weeks ago, and from what I gather is still going strong!

    Oh, and rather than chop up the nice SGI cable I got a 13W3 connector
    off a broken Extreme board (any old SGI graphics board should do) and
    a VGA lead off a broken PC monitor and wired them up together
    according to the cable specs for each. These went into a little
    project box so I had a neat solution. Good soldering skills are a
    must though as the signals need to be clean, and you don't want bits
    of old solder dropping into the circuitry! Also monitor safety is a
    big issue too as there's a heck of a lot of volts flying around a huge
    monitor like that, even after it's been turned off (the tube is
    basically a huge capacitor - just don't touch it or the circuit board
    pins with your fingers!).
