Open Source Software
From TechPubs Wiki
SGI and the community have offered several flavors of "ware" for IRIX. A list of them and what they focus on is here.
For IRIX 6.5
IRIX 6.5 by far has the most editions of software for it. Nekoware, SGI Freeware and SGUG RSE
For 6.2/5.3
TGCWare has set the bar for this. As it has been frozen since the 2010s, we linked to the IRIXNet mirror.
