SGI IRIS

**IRIS** oli Silicon Graphicsin (SGI) työasemasarja, joita olivat 1000, 2000 ja 3000 -sarjat. Työasemissa käytettiin Motorola 68000 -sarjan suorittimia.

IRIS GL -grafiikkarajapinta sai alkunsa sarjan työasemilla, joka johti OpenGL:n kehitykseen.

1000, 2000 ja 3000 -sarjojen jälkeen SGI siirtyi MIPS-arkkitehtuurin suorittimiin ja julkaisi muun muassa 4D/20 Personal Iris -sarjan työaseman.
