The Autochanger Controller PCA
The autochanger controller PCA contains the following major components:
•
microprocessor
•
autochanger ASIC
•
NCR 53C80 Chip (SCSI bus control)
•
flash EEPROM
•
RAM
•
SCSI interface
Figure 6–2 Autochanger Controller PCA Block Diagram
The MICROPROCESSOR is a Motorola MC68EC000 running at 12.288 MHz.
This microprocessor controls all processes on the controller PCA such as servos,
SCSI interface, and commands to the control panel.
Associated with the microprocessor is clocking circuitry, RAM with standby
power supplied by a capacitor, and ROM.
The AUTOCHANGER APPLICATION-SPECIFIC INTEGRATED CIRCUIT
(ASIC) provides the processor interface, programmable features, and a servo
system.
