Haha that was because the base Indy was shipping with 16MB of RAM and IRIX 5 was too bloated for that to be usable. Meanwhile everyone with Indigos kept running

Haha that was because the base Indy was shipping with 16MB of RAM and IRIX 5 was too bloated for that to be usable. Meanwhile everyone with Indigos kept running IRIX 4 until things got better around 5.3. The Indy had XZ graphics available, which I believe were the same as the top Elan option available on the Indigo (4 GEs)
