EXTENDING THE CD-I SYSTEM
A number of options are available to extend the basic  functions  of  the
CD-I system. The use of the features are completely dependent of the  ap-
plication on your CD-I disc. The CD-I system had been  designed  to  work
with the following options.

A personal Memory Card can be inserted in the  MMC  module.  It  con-
tains a battery back up memory module, e.g for use as an extension of the
build-in NV-RAM, (Non-Volatile Random Access Memory).

An RS-232-C connector block will extend  the  CD-I  system  with  a
RS-232-C serial interface that can be used to connect a modem, printer or
can be used as a port to another device (application dependent).

The CD-I expansion module CDI 182 with the  same  exterior  design
as the CD-I player and the MMC module, provides full access to the video,
audio, text and data processing capabilities of the CD-I MMC module.
