46 DB15 Connector (Game Port)
DB15 Connector (Game Port) 3
The DB15 connector allows you to connect MIDI devices to the card. It also allows you to
connect a PC-compatible joystick, which can be used as a game controller. See Figure 3-1
on page 34 for the location of the connector on the 12" card, and Figure 3-2 on page 35 for
the location of the connector on the 7” card.The joystick can be used only with programs
running on the PC side of the system. You should refer to the user’s guide supplied with
your Macintosh computer for information on installing a joystick or MIDI device. Table
3-5 lists the pin assignments for the connector.
GIMO Connector 3
The GIMO connector is a 16-pin connector on the PCI card that enables you to connect a
monitor to the 12” or 7” card, provided that the CPU in which the card is installed has a
GIMO connector and a Berlin adapter card. The video connection is made by means of a
ribbon cable that plugs into the GIMO connector on the card and then plugs into the
Berlin adapter card in the CPU. This cable also carries the audio input and output signals
when the card is installed in systems that do not have discrete audio cables.
