Core bus controller and I/O subsystem as present on newer HP 9000/700
workstations and single-board computers. The supported core bus controllers
are those used in conjunction with PA7100LC, PA7300LC and early PA8000 /
PA8200 CPUs and based upon LSI's macrochip that includes:
- Core bus controller
- System Clock
- Interrupt Controller
- Real Time Clock Interface
- Power System support
- RAM and Flash EEPROM controllers
- Two PS/2 ports
- RS-232 and Centronics I/O ports
- i82596CA LAN coprocessor
- NCR53c710 SCSI I/O processor
- Serial Interface for the CS4216 Audio Codec
- Interface for the WD37C65C floppy drive controller
- Optional Telephone interface (two fax/voice modem channels)
