1. General Function
The PH-GT09 (GT) circuit card provides both the TSW I/O Local bus and the MISC bus interface. The
CPR controls TSW, PLO, DLKC, and MISC via the ISAGT and GT.

SN1455 CPRAQ-A/SN1531 CPRAS-A
CPU Board
1. General Function
The CPR consists of the following components.
(a) CPU BOARD: Contains the Main Processor Unit (MPU), ROM, and 128 Mbyte of Random Access 
Memory (RAM). This board may also contain the ISAGT (PZ-GT13/PZ-GT20) on 
its Industrial Standard Architecture (ISA) bus, and LANI (PZ-PC19) on the 
Peripheral Component Interconnect (PCI).
(b) DSP: Contains the CPR switches and the CPR status indicator lamps.
(c) FDD/HDD:  Floppy Disk Drive (FDD) and Hard Disk Drive (HDD) are mounted on a circuit 
card, which, if necessary, can be extracted and/or inserted while the system is in 
operation.
(d) PWR:  Supplies the operating power to the CPR and also the MISC slots of the LPM.

2. Mounting Location/Condition
The CPR is composed of the CPU BOARD, DSP, FDD/HDD, and PWR and is located in the Local
Processor Module (LPM) as shown in Figure 2-10. Since the CPR provides the Industrial Standard
Architecture (ISA) bus and Peripheral Component Interconnect (PCI) bus, the ISAGT and LANI cards are
located in those busses respectively.

STATUS
(DSP)Two sets of “7-segment LED” show the CPR processing status. The CPR processing status is determined by the 
SENSE switch settings, and the new processing status starts when the CPURST switch is pressed. The 7-segment
