AST VGA                                             AST Part Number 202249-001

The AST VGA is a Video Graphics Array video adapter for use with the IBM PC,
PC/XT, PC/AT, and 100% compatible machines.  It comes standard with 256K of
video memory and a 15-pin connector for sending analog video signals to a
PS/2, VGA, or Multisynch monitor.  Video modes supported by the AST VGA are
MDA, HGC, CGA, EGA, and VGA, all on analog monitors.


JUMPER SETTINGS

    The AST VGA has only one user-configurable jumper setting; a three pin
    jumper that must be connected on the left or right pair of pins depending
    on the kind of monitor connected to the adapter.

    The left pair (1 & 2) of pins should be connected if the monitor is a PS/2
    or other analog only VGA monitor.

    The right pair (2 & 3) of pins should be connected if the monitor is a
    Multisynch monitor.  Note that the Multisynch must be set for analog
    operation.  Most Multisynch monitors come with a standard 9-pin TTL cable. 
    If this is the case, a 9-pin to 15-pin adapter cable must be obtained from
    the manufacturer of the monitor.
