2. The IRIS Indigo Workstation

The IRIS Indigo workstation was designed to be easy to set up, easy to use, easy to maintain, and easy to upgrade. The central unit, monitor, keyboard and mouse, and the various add-on pans that make up the IRIS Indigo system have all been designed with the user in mind:

• Boards and internal devices are easy to access. Boards are accessible through the front panel without the use of a screwdriver, making memory upgrades fast and simple. No cables or screws are needed to add capability to the unit.
• Internal SCSI devices are self-configuring, and slide into and out of their slots in seconds.
• An internal speaker is included for sound output, and a a microphone is provided for soundinput
• Iconic labels are on all input and output connections, for intuitive, international recognition.
• Entry IRIS Indigo R3000A is a Class B device rating for RF emissions on both the central unit and the monitor. All other Indigo CPU and graphics configurations are Class A devices.
