Configurations
The units came in at least two and possibly more configurations with a song-compositing subsystem and a sprite-design subsystem as an option.
One configuration option adds a port labeled "MIDI" that contains a standard MIDI jack (though it's not known if the port is actually MIDI compliant), and a single RCA-Style connector in red. Investigation of the internal circuitry of the device suggests that this RCA jack is used to record sounds into the device for use in music composition.
Another configuration option adds a port called "Analog RGB", and presents a female DB-9 port. Internal circuitry again suggests that the port is an EGA port, though is probably closer in design to the ports used in Commodore 128 computer.
