67 MHz POWER2 based workstation.  Seems to have been on the high end in 
its day.

I'll have to look into a VGA adaptor for the frame buffer, then.  Or,
(as Dave mentioned) find an SGI monitor.  The former is more likely to
happen.  Since I have no monitor, I'm using serial.  I actually don't
expect to run a head on the box, anyways -- just trying to get the thing
going.

You're kidding.  The diag mode has to be -loaded-.  Great. :(

Seriously?  There's nothing output to the screen until later in the OS
boot stages?

Ugh.  So, I have to ask, is there anywhere I can get install media for
cheap?  A quick eBay scan reveals I'd have to pay between $100 and $200.
That's a bit rich for me right now.

Might be worth it for the archives.  I'm sure I won't be the last to ask
this question...

Thanks for the response!
