*1 When pins 2, 4, and 6 are used, connect each pin to SCSI-ID (-).
*2 When pins 8, 10, 12, 13, and 14 are used, connect each pin to GND.
*3 This signal indicates that a cartridge is inserted in the device. This is a TTL
level signal.
H: A cartridge is present.
L: No cartridge is present.
*4 This signal is used to instruct cartridge ejection from outside.
