Over the weekend, having gotten a beautiful, perfectly circular round
tuit, I cracked the root password on my SGI Indy (tip of the hat to Doc
Shipley) and got the system fully operational. It's a little poky, so I
suppose the next thing is to upgrade the CPU module and get a 24-bit video
card in it (8-bit is yugly).
However, in the meantime, I'm using a cheapo 13w3 to VGA converter that works
okay with my NEC monitor, but there is still a sync signal on the green
line, leaving me with a persistent green tint. Reducing green gamma in IRIX
helps some, but I'd like to get my black back (because once you go black,
well, you know). What are people using to turn SOG into a more conventional
sync signal an off-the-shelf multisync monitor like my NEC XV15+ VGA display
will accept?

You may want to investigate the LM1881--this seems to be popular with
XBox users hooking up to VGA, since the XBox is SOG.
Or, you could simply find a VGA monitor that accepts SOG. My NEC
MultiSync LCD 2010, for instance, does.

I see some circuits based on that. Should be easy to build.

One site alleged if you clip pins 11-15, NEC monitors will use SOG
instead. Any truth to this? I have a lot of VGA cables sitting around
doing nothing, so I might try this unless people know it's hooey.

I use a LM1881 based circuit to hook a Samsung on my HP 9000/380 system.
Works fine.

I use older Sony Trinitron monitors with my old 68K macs that like SOG.
There are probably a few people in your area that would love to ditch an old
tube monitor.
