                            BOCA SuperX VGA

    BOCA has added several video cards to their line. I looked at the
    SVGAX2 and the SVGAX3. Both cards are identical, with one exception.
    The SVGAX3 was actually created for Windows users. It features bit
    block ("BitBLT") transfers for GUI acceleration.

    Both cards have 1MB video RAM, support ISA and EISA systems. Display
    24-bit True Color with a 72Hz maximum refresh rate. Generate up to
    1.8 million colors in 640x480 resolution, up to 65,536 in 800x600,
    up to 256 in 1024x768 and up to 16 colors in 1280x1024.

    They have drivers for many DOS applications including AutoCAD,
    AutoDesk, Ventura, WordPerfect, WordStar and others. It will also
    support 132-column mode in 16 colors. Both also have Windows High
    Color and True Color Drivers, and the SVGAX3 has the additional
    BitBLT drivers for Windows.

    I ran WinTach v1.2 on the SVGAX3. The test was done in 640x480 w/256
    colors. It was done with both a 486DX-33 and Intel OverDrive chip:

                w/486DX-33          w/OverDrive
    WP          4.30                6.70
    CAD         5.52                8.44
    SpreadSheet 5.32                6.70
    Paint       5.14                7.28

    Overall     5.07                7.28

    The cards are 16-bit, and display in both interlaced and
    non-interlaced modes. The software is provided on high-density 3.5"
    diskettes. OS/2 and SCO UNIX/XENIX drivers are under development.
    BOCA has a BBS, or you can get the latest drivers from CompuServe or
    GEnie.

    There is also a feature connector, that provides an interface to the
    video and timing signals, between the CPU bus and the video card. It
    also enables connection to 8514 devices, co-processor cards, and
    multimedia products.

    I was pleased with this card. I have not experienced any problems,
    and have recommended the card to others. As with all BOCA products,
    they are Made in the USA, and come with a 5-year warranty.
