4. Graphic Control
This Graphic Control can be used in combination
with your CD-I system as an alternative to the
CD-I remote control. It offers faster control and
input of graphical data for graphics-based
applications;
5. Memory card
The Memory card can be inserted in the MMC module.
It contains an NV-RAM (non volatile) for use as an
extension of the built-in NV-RAM, to personalise
the system. The use is completely dependent on the
application software to be developed.
6. Expansion module
The
main function of the Expansion module is to
enhance the CD-I system (MMC module and CD-I
player module) with capabilities beyond the
typical base case CD-I system.
The Expansion module incorporates two floppy disk
drives to store or read data conforming to CD-RT0S
(0S-9) disk format.
For connections 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 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. System RAM
extension and SCSI interface extension boards are
supplied.
Within a CD-I system, only one Expansion module
can be connected, to be placed directly below the
MMC module.
