Genesis MP
Appendix A
External Connections
This chapter describes the I/O features of the Genesis MP and the
interfaces for external I/O devices. The interfaces and their pinouts
are listed below.
Note:
The A/V features and specification that are specific to the 3 slot
Genesis MP are described in Apple’s Technical Information manu-
al. This manual was included with the Power Macintosh that was
used in the Genesis MP conversion process.
Interface Basics
Follow these guidelines when handling, disconnecting, or connect-
ing the system:
• When connecting or disconnecting a cable, always hold the
cable by its connector (the plug, not the cord).
• Always turn off the system and all of its components prior to
connecting or disconnecting any cables or when adding or
removing any component. Failure to do so could seriously dam-
age these assemblies and/or the system. Additionally, electric
currents can cause damage to oneself or even loss of life.
• Never force a connector into a port. If the connector and port
do not join with ease, they may not match, or may be in
need of repair. Ensure the connector matches the port and
that the connector is correctly aligned to its pin assignments.
Also check to ensure that none of the pins are bent.
Refer to the Genesis MP User Guide for more information about
connecting External SCSI devices. For information about
Installation, SCSI Cables and Chains, and Termination, refer to
Chapter 3 of the Genesis MP User Guide.
I/O Ports
The Genesis MP system has the standard I/O ports found on all
Mac OS systems:
• Two Geoport-compatible serial ports
• ADB port
• Ethernet ports (AAUI and 10BaseT)
• SCSI port
• Stereo sound input and output jacks
