Indigo 2

Silicon Graphics Home

Overview

The Indigo 2 was the first Silicon Graphics machine I acquired. I would like to add the purple model with high impact graphics to my collection one day. 
My system has a 150 MHz R4400 with 128MB of RAM and GR3-XZ Graphics. XZ was also known as Express graphics. The graphics board set is made up of 2 boards sandwiched together. It has 2 Geometry Engines, 1 Reality Engine, and a Z Buffer, with 24-Bit color.

It has Irix 6.5.22 installed on a 36 GB SCSI hard disk. I don't have a lot of 50 pin SCSI disks, so I used an adapter to go from 50 pin SCSI to 80 pin SCA, since I have a lot of SCA drives from old servers. It's tight and it bends the hard disks board a little, but I haven't had any issues.

When I first got the system, the graphics output had an issue. the screen was covered with vertical lines, but the mouse cursor was on top of the lines. Thankfully, all I had to do was split the graphics board set and reseat all the connections to fix it.
