completely random SGI info

This page is primarily for my own personal reference. If you find it useful that's cool, but there are many other sites out there with MUCH more info than this. Some of them are listed at the bottom of this page. The focus here is pretty much on 1991-2003 MIPS/IRIX systems (primarily post-R3000 stuff).

IP numbers:

Odd numbers indicate server class, even numbers indicate workstation class. This rule of thumb doesn't seem to hold up as well any more with the IP53/IP35.

Model/Marketing numbers:

CMN A010 Onyx (rack)  
CMN A015 Origin 2000 (deskside)  
CMN A018 Origin 200  
CMN B003 Indigo  
CMN B006 Indy  
CMN B007 Indigo2  
CMN B014 O2 found on bottom
CMN B015 Octane/Octane2 found on back
CMN 016 Origin 300 found on top
CMN 026 Origin 350 found on top

I only list the above model numbers if I've been able to verify them in person. There's only one example so far that I've seen with my own eyes that doesn't fit the pattern, and I'm trying to make sense of it. I have seen plenty of Octanes and Octane2s with the "CMN B015" number as you'd expect... but I have now seen two Octane2s with a "CMN B014" number (they were ANG400s sitting right next to other ANG400s with the expected B015 string). I'm not sure what to make of that. The only pattern observed looking at 5 identical Octane2s was that the ones made in late 2000 were 15's and the ones made earlier (prior to September) were 14's. Strange? Yes.

O2 CD-ROM drive numbers:

I have used Toshiba XM-6401B CDROMs on my Indigo2 (external) and Origin200 (internal) with no problems. This is a 40x drive. I still want to try to more tests... replacing the 5701 in my O2 with a 6401 (internal) and then adding a 6401 to my Octane2 (external), I don't anticipate any issues, but you never know.
