Philips CD-I - Expansion Module Introduction and Precautions

7-1. Introduction
The CD-I player system, to which this Expansion module
belongs, is a microprocessor system which can handle
sound, video and computer code data.
The main function of this Expansion module is to
enhance the CD-I player system (MMC module and CD-I
player module) with capabilities beyond the typical
base case CD-I system.
Within a CD-I player system, only one Expansion module
can be connected, to be placed directly below the MMC
module.
The Expansion module incorporates two floppy disk
drives to store or read data conforming to CD-RT0S disk
format.
For connection of additional (non-system) equipment the
expansion module provides a Centronics parallel . printer
interface and RS-232C serial interface. The RS-232C
serial interface can be applied for a modem or a
printer , or as a port to another data processing
system.
To expand the system, two slots for extension boards
are provided. These slots are connected to the CPU bus
signals from the main 68070 microprocessor in the MMC
module. All extension boards can be connected to either
slot.

that given on the type plate in the rear of the
Expansion module.
