DESCRIPTION
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
