I think this is unfortunately just a name clash. SGI's first generations 
of machines was called "IRIS" and ran an operating system called 
"GL2-WX.Y" where X.Y is a version number. GL-W2 is a System III unix 
port. The graphics subsystem was called "IRIS Graphics"

I'm quite certain it isn't. But I'd be happy to be proven wrong, maybe 
Convergent rebranded SGI's machines. It is not unheard of:
