The IRIS Crimson (code-named Diehard2) is a Silicon Graphics (SGI) computer released in 1992. It was SGI's first 64-bit product released to market, as well as one of the earliest 64-bit workstation and UNIX servers available.
The Crimson is a member of Silicon Graphics's SGI IRIS 4D series of deskside systems; it is also known as the 4D/510 workstation. It is similar to the Power Series workstations, sharing the same deskside chassis. It can use a wide range of graphics options (up to RealityEngine). It was also available special order as a file server with no graphics.
This machine makes a brief appearance in the movie Jurassic Park (1993) where Lex uses the machine to navigate the IRIX filesystem in 3D using the application fsn to restore power to the compound.[1][2] The next year, Silicon Graphics released a rebadged, limited-edition Crimson R4400/VGXT called the Jurassic Classic, with a special logo and SGI co-founder James H. Clark's signature on the drive door.

- One MIPS 100 MHz R4000 or 150 MHz R4400 processor[3]
- Choice of seven high-performance 3D graphics subsystems (Entry, XS, XS24, Elan, Extreme, Reality Engine, VGXT)
- Up to 256 MB memory and internal disk capacity of up to 7.2 GB, expandable to more than 72 GB using additional enclosures
- I/O subsystem includes four VMEbus expansion slots, Ethernet and two SCSI channels with disk striping support
Crimson memory is unique to this model.
