SGI O2 R5000-200

Manufacturer	SGI
Model	O2 "Moosehead"
Available	1996/10/10 - 2002/09
CPU	150-400MHz R5000/R10000/R120000
Memory	32MB - 1GB
OS	IRIX 6.3, 6.5.x
Disk	onboard SCSI (1GB-18GB)
Network	onboard Ethernet (10/100Mbit/s)
Expansion	1x PCI (33MHz/64bit), proprietary AV
Description	The O2 is an entry level SGI workstation in the typical modular designer case. It uses a unified memory architecture (UMA), there is no separate graphics memory. 3D calculations are done in CPU, but it has special hardware for certain operations, allowing it to perform real-time audio and video processing.
Marketing	An extremely high-bandwidth memory architecture, dedicated engines for image and video processing, and a suite of digital media tools give the SGI® O2 workstation unrivaled capabilities for digital media creation and manipulation, including video and audio capture, playback, editing, compression, and decompression. This paper addresses high-level O2 system features, underlying technology, software tools, and applications related to video, audio, and compression.
Story	I bought this one at the flea market at the Vintage Computer Festival in Munich.

This machine

This machine has a 200MHz R5000SC (32KB I, 32KB D, 1MB 2nd level cache), 640MB of RAM, the analog video option, and is currently running IRIX 6.5.28.

The blue designer-case gave it the nickname "vacuum cleaner"
