U24 63G9143 is 37RGB061L-17CC

The SIMMs are 162-pin, 40H3581, four chips on front, one on back, IBM025161LG5D-70 directly soldered to the PCB via a "saddle".


Three different classes of 3D graphics adapters:

  • Class I - does not provide unique hardware for 3D graphics operations. Provides a frame buffer and all graphics processing is done by the system CPU.
  • Class II - provides hardware rasterization for 3D graphics functions and relies on the system CPU for geometry processing.
  • Class III - performs all 3D graphics processing including hardware support for rasterization and 3D geometry.

The GXT500 and GXT500D are IBM's first implementation of a Class II graphics adapter. These class II solutions utilize IBM's powerful PowerPC processor to drive the graphics geometry pipeline and the new GXT500 and GXT500D to perform 3D rasterization of graphics functions. The benefits derived from this design are scalability of graphics performance with CPU performance and lower cost 3D graphics hardware.
   The GXT500 and GXT500D provide support for state-of-the-art graphics functions like hidden-line/surface removal, antialiasing, Gouraud shading, depth cueing, transparency, texture mapping and accumulation. They support display resolutions of 1,280 x 1,024 and 1,024 x 768, including support for monitors that comply with Part 3 of the ISO 9241 ergonomic standard. This standard provides users with improved viewing, reduced-flicker images, minimized reflections and sharper characters.
   Stereo viewing is supported on both the GXT500 and GXT500D. Stereo viewing is a method used to add depth to an image rendered on the 2D surface of a monitor. The method supported is the Crystal Eyes** system by StereoGraphics Corp. A pair of LCD glasses and an IR transmitter are required and must be purchased separately. Notice: When installing or using a StereoGraphics transmitter for 3D viewing, use only a transmitter manufactured for attaching to the IBM GXT500 or GXT500D graphics adapters. It has a BNC and DB-9 connector. Other models of the transmitter have only a DB-9 connector and will not work with the GXT500 and GXT500D.
   AIX Version 4.1 is required for support of the GXT500 or GXT500D on the Models 42T and 42W. On the Models 41T and 41W either AIX/6000 Version 3.2.5 or AIX Version 4.1 is required.

GXT500 and GXT500D Support:

  • The display of up to 16.7-million simultaneous colors
  • 60 to 77Hz Refresh Modes (on appropriate displays)
  • Stereo viewing
  • Single card, 60x bus attachment
  • Four hardware color maps
