SGI O2

In September 2009 I started to downsize this collection to a few items and then archived this section to its own subdomain at the start of October 2011.

This system

In January 2006 I spotted an offer on one of the mail lists at work for a number of unwanted SGI systems, to be exact four different Indy's and an O2. Luckily I responded quick enough for my request for the R5000 Indy and the O2 were accepted.

The O2 system is the lowest CPU model (180Mhz R5000 with no L2 cache) but it does have the full I/O module and 256MB of RAM. The peripherals I got with is include a SGI branded 20" display, keyboard and mouse, and the (apparently rare) O2 camera.

In April 2007 I acquired a SGI 1600SW display with a MultiLink Adapter which became part of this system, replacing the 19" CRT.

The rear of the unit contains the standard assortment of ports (video, mouse, keyboard, parallel, scsi, etc) while on the left side (when viewed from the front) features an array of audio and video inputs and outputs. This is a R5000 CPU model which means it has two hard drive bays (only one is populated). - o2-04.jpg o2-04.jpg, 1600x1200, 276KB

The mainboard, hard drives and I/O module simply slide out of the chassis once their retaining lever is released. The flat black piece of metal slots into the rear of the unit and when a lock (laptop type) is attached the removal of these modules is prevented. - o2-05.jpg o2-05.jpg, 1600x1200, 304KB

A view from the rear of the empty chassis once the modules and power supply have been removed. Apart from the backplane that connects the modules together the only component that remains is the CD-ROM drive in the upper section. - o2-06.jpg o2-06.jpg, 1600x1200, 284KB

The black top piece of the skin can be removed by releasing a catch near the power supply. At this point it is possible to remove the blue section of the skin which would allow the CD-ROM drive to be removed. - o2-07.jpg o2-07.jpg, 1600x1200, 265KB

Removing the PCI bracket exposes more of the logic board including the CPU module which contains a 180Mhz R5000 CPU. - o2-09.jpg o2-09.jpg, 1600x1200, 419KB

A closeup of the ports on the motherboard module. From left these are SCSI, parallel, VGA (standard DE-15, not 13W3), ethernet, two serial, keyboard and mouse. Above the video and parallel ports is the space where the adapter for the <a href="http://www.sgi.com/products/legacy/displays.html" title="SGI - Legacy Products: Displays">SGI 1600SW display</a> is installed and above all of the ports is the back of the PCI slot. - o2-10.jpg o2-10.jpg, 1600x1200, 344KB

A closeup of the locking lever for the motherboard module. A pin inside the chassis runs along the slot on the back of the module until it fits into the lever. When the level is closed it pulls the module into the case as the pin moves along the curved slot. The hard drive and I/O modules have a similar mechanism. - o2-11.jpg o2-11.jpg, 1200x900, 211KB

This I/O module provides both input and output for S-Video, composite video and sterero audio. The last two ports on the side are for headphones and a microphone and the rear of the module contains an audio line-out and the port for the O2 camera. - o2-12.jpg o2-12.jpg, 1200x900, 194KB
