Got my SGI Crimson up and running on serial console, and I've got an
old SGI monitor sitting around, but I guess I gave away all my cables.
Anyone have such a cable in their junk bins? Only ones on ebay now
are from the dealer-gougers.

I use mine with an "ordinary" (i.e. Non-SGI branded) 21" CRT with a
5xBNC-VGA cable. One of the sync leads (H-sync I think) is redundant, of
course.
Suitable items found just now on ebay.co.uk:
270198917710 - 5xBNC-VGA Cable @ ?4.99
280189417939 - 21" Dell CRT Monitor @ ?19.99
Not a bad setup for ?25! Just by way of an example of course - I realise
you're not in Grimsby, UK ;-)
Would the Sun 13W3-BNC leads not work? I know there's a subtle difference
between Sun and SGI monitor cables, can't quite remember what it is. They
seem cheap and plentiful enough:
230206161455 - Sun13W3-4xBNC @ ?7.99.

I did see the Sun cable with the 4 BNC on US ebay and thought the
same. I'm not sure if that fourth lead is relevant.
My alternative is to haul an LCD panel down to the Crimson and start
experimenting with various 13W3-VGA adaptors.
Still steamed at myself for giving away cables for equipment I was keeping!

Still, at least you've got one of the finest and most interesting computers
ever sold by SGI to cheer you up! I love mine - it's the pride of my
collection and adds real presence to my office, sat beneath my MacPro. It
also doubles as a magnificent space heater in the winter months!!

Indeed, it is mighty pretty too! Mine is the "server" model, going by
the label on top, yet it has a 13W3 graphics card. I believe the
Server had no gfx at all? Now inside the door I also found an "Elan"
tag with the glue worn off, so I'm guessing it may have gotten a field
upgrade, video card and label.
I've got a dead Iris 410/VGXT downstairs. Wonder if I can transplant
the gfx board from that into the Crimson?
Anyone tried to use external SCSI on a Crimson (or Iris?) Mine has
all the drive bays full (3 HDD and a 150mb tape) and I'm trying to get
a CDROM hooked up temporarily so I can reset the root pw on the drive.
There are two external SCSI connectors. If I attach to the left
one, I lose my hard drives (and still no cdrom seen in 'hinv.') If I
attach to the right one, nothing.

As I understand it, that's correct. But on these systems you can add
a graphics card to it.
Is yours marked "Jurassic Classic"? Mine is :-)

Oh, a VGXT. I've wanted one of those in my collection as its the
first SGI machine with hardware texture. I'm still fuzzy on what the
difference is between a Crimson and a VGXT, aside from the graphics
bits.

I haven't tried it yet on any of my machines, but I'd be interested to
hear the results of debugging your issue if you get it working.
Is it possible that the SCSI device IDs are fixed and that's why
connecting an external device makes your HD disappear?

VGXT is a graphics board set, Crimson is a machine. Crimson can be
equipped with the VGXT board set. The IRIS 410 is a single MIPS 3000
deskside machine, quite like the Crimson, only brown. The difference
between Crimson and the 4x0 IRISes is that Crimson is an R4000
machine, while earlier ones are R3000.
No, they aren't fixed. But SCSI can be set up in a couple of ways in
Crimson, putting some of the internal bays on either a single bus or
divided between them. This has an impact on how termination should be
handled (terminators on the connectors at the bottom). I don't carry
the Crimson user guide with me on holiday, but I'll be glad to look up
the particulars when I get home next week.

May it be possible that the Crimson uses High
Voltage Differential SCSI
for its disks like some HP9000 server class machines? In that case a
Single Ended device will look up the bus completely. Check the model
designator on the disks if they are SE or HVD...

Yes, if
you use sync on green. The pinout on the coax pins is the same
on Sun and SGI (and IBM). The difference is in the 10 small pins for
sync and monitor ID. All SGIs with 13W3 connector that I had in my hands
supply sync on green. So if your monitor supports sync on green just
connect the three RGB BNC connectors and you are done.
You can't do this with Suns. Usually they don't supply sync on green.
You need the extra pin with the csync signal. So you must use a 13W3 to
4 BNC cable with Sun pinout. But you can solder a 470R resistor from the
csync to the G pin and make your own sync on green. I've done this on
one or two TGX SBus framebuffers.

Whoa.....my old Hitachi model ?? 19" monitor and the first VGA-13W3
adaptor I grabbed out of the drawer actually worked! I should
probably still look for one of those cables, though...
Now to deal with the cdrom issue.
