    Arrgghh... the MG24 was discontinued in '96, so we'll see...

    The 7237 graphics adapters for the RS/6000* workstations are adapters
    supplied by non-IBM companies. Models 001, 002, and 003 are the Freedom
    Series 6000* graphics accelerators, and model 024 is the Megatek M24
    graphics adapter for 24-bit color capability. See the individual model abstracts for details.

    Model Description 7237-024

    The Megatek Mg24 Graphics Adapter Model 024 provides 24-bit True Color capability to most of the RS/6000 family of products. The Megatek Mg24
    requires one Micro Channel slot in the RS/6000 workstation and is
    supported by the 7011-200 series, 7012-300 series, 7013-500 series, 7006
    41T and 41W, and 7030 3AT and 3BT systems.

    The Megatek Mg24 Graphics Adapter helps the customer unleash the power
    of the RS/6000 workstation to solve the need for accelerated drawing
    speeds and added True Color capability with this 2D, 24-bit graphics
    adapter.

    END USER PRODUCTIVITY--Improved Worker Productivity:

    Megatek Mg24 Graphics Adapter is designed to provide 2D 24-bit graphics capability at accelerated speeds on the RS/6000 workstation. Its ability
    to do large-area erases and fills in frame buffer makes it ideal for
    desktop publishing, imaging mapping, medical, and any other area where performance and real-color representation are required. With support for
    24 bits per pixel single buffering, it can provide 16 million
    displayable colors.

    3D capability is possible by using the AIXwindows* 3D feature. This
    feature provides 3D function through software via Softgraphics that is
    included in the feature. Softgraphics is a complete software
    implementation of OpenGL**, PEX, and PHIGS. Refer to software
    announcement 293-489, dated September 21, 1994, for specific programming requirements.

    The Megatek Mg24 is supported on a wide range of RS/6000 workstation
    models, allowing users to add 24-bit True Color capability to existing
    systems as well as to new systems. It provides support for a variety of
    IBM displays.

    A conceptual architecture of the Megatek Adapter consists of the
    following major modules:

    P9000 Graphics Processor Module: This module performs graphics
    primitive drawing, such as vectors, polygons, and text scrolling.
    Micro Channel Interface: This module controls the interface with
    the Micro Channel bus. This module provides interupts and control DMA operations to the adapter.
    Frame Buffer Memory: This module supports simultaneous 24-bit single-buffered and 8-bit single-buffered graphics. The 8-bit and 24-bit windows can exist simultaneously on the screen. It is desired that the implementations also provide a flexible memory architecture for
    supporting a range of video resolutions.
    PROM: This module provides basic functionality to allow the adapter
    card to perform some initialization functions as well as contain product information.
    RAMDACs: This module fetches the 24-bit and 8-bit data from the
    frame buffer and produces suitable, formatted RGB video output to the
    display. This module also contains the color look-up tables and hardware
    cursor functionality.
