[SunRescue] parts I'm parting with!

[Mike Hebel]

It totally depends on the model of the monitor.  I believe (I may be wrong
here) that the 17" ones work on some systems.  Most of the time the
Sync-on-green issue is what stops the cross-usage from SGI to Sun and back.

Check out the links below.

I may be incorrect.

Sincerely,

Mike Hebel

i didn't really read this whole thread, but am i to understand that a
stock SGI monitor with a 13w3 type connector on the back will not work
with, say, an IPX?  i need to know before i might pick up a spare from
work for home.
