Indy
Overview
The Indy is my favorite Silicon Graphics machine, just for the case design. I love the color, the speckled finish, and how the case looks like its fractured horizontally.
The Indy is well known for being underpowered, an "Indigo without the go". I agree with that sentiment after using it when compared to my Indigo 2.
This Indy has a 100 MHz R4600 CPU with FPU, 96MB of RAM, and 8-bit graphics. It has Irix 6.5.22 installed on a 9.1 GB SCSI hard disk. Irix 6.5.22 is the latest version of Irix that will run on the Indy and other IP22 architecture machines.
Overall Irix is a very nice Unix, and the 4Dwm window manager feels very snappy, even on the underpowered hardware.
