Looks to be the same part. Mine's slightly older - 030-1872-005 Rev. A. Presumably the boards are interchangeable between the systems, then. That would allow someone to convert an Origin 350 over to an Onyx4 G2N if they had an AGP riser.

Eeeuw, stinky ! How about changing an Onyx4 back into a nice O350 ? 

The TIO is an Altix-specific I/O ASIC used as a part of SGI's efforts toward reconfigurable computing. Maybe that version is designed to provide higher bandwidth for specialty applications?

Since you're here and we're talking interchanges, would you consider swapping the IO9 in your O350 for the IO10 from the Altix to see what it does ? I remember that the SATA interface on the 10 wasn't that great, but still, it'd be an interesting parts-swapping experiment to see if you could get an all-in-one sata interface (maybe for a dvd-rom ?) into the O350 ....

You nudged my memory on the G2. Plan was, two more boxes, just i/o, riser, and v12 in each, two numalinks between a pair of compute modules with v12's, and two xio links between the computes and the additional graphics bricks. Should work, no n-brick required.

All to drive one monitor, but still might be fun.

Anybody running an Onyx4 want to report in on how well it works with SGI graphics ? Reports at the time were, lots of glitches and stuff that wasn't quite right. But you know people, if it was just a flash when changing windows or something, a single O4 would do this job much easier than a four-box pileup.
