Overview
The 745 industrial systems are 744 VME boards in a heavy VME case, which provides the neccessary I/O facilities:
- Room for up to four SCSI devices, which can be accessed from the outside
- Four-slot EISA or PCI cage
- Room for PCI-mezzanine expansion cards, via special PMC bridges/expansion
Internals
CPU
- 745/132L: PA-7300LC 132MHz with 64/64KB on-chip I/D L1 cache
- 745/165L: PA-7300LC 165MHz with 64/64KB on-chip I/D L1 and 512KB off-chip unified I/D L2 cache
Chipset
- LASI ASIC, which features:
- NCR 53C710 8-bit single-ended SCSI-2
- Intel 82596CA 10Mb Ethernet controller
- WD 16C522 compatible parallel
- Harmony CD/DAT quality 16-bit stereo audio
- NS 16550A compatible serial
- Wax chip
- EISA bus converter (GSC-to-EISA)
- Second RS232 serial
- Dino GSC-to-PCI bridge (on the PMC expansion adapter?)
- Phantom PseudoBC GSC+ port
- Visualize-EG (
Graffiti
) graphics - Intel 82503 Ethernet transceiver, media auto-selection
- CS4215 or AD1849 programmable CODECs
- VME controller (
Backplane controller ASIC
) - PCMCIA controller
Buses
- GSC bus
- Optional EISA bus
- Optional PCI-32/33 bus
- VME bus
- SCSI-2 Fast-Narrow single-ended bus
Memory
- 16-256MB special ECC mezzanine cards (same as for the 744 VME boards)
- Up to four cards can be installed
- 16MB minimum, 1GB maximum amount of RAM
Expansion
- Two sites for GSC-mezzanine (GSC-M) cards, requires the A4219A GSC Expansion kit or
- Two sites for PCI-mezzanine (PMC) cards, requires the A4504A PMC bridge board
(two additional PMC sites can be obtained through the addition of the A4509A PMC Expander board to the above). The PMC bridge/expander boards connect to the VME backplane on a VME slot above the 744 processing board. However they probably use the GSC bus routed through the VME P1/P2 connectors, and not the VME bus. - Either four EISA or four PCI (5V) slots in a separate I/O cage
Drives
- Four bays for external-accessible SCSI (SCSI-2 Single-ended) drives
- One bay for a 3.5″ SCSI drive
External connectors
- 50-pin HD SCSI-2 Fast-Narrow single-ended
- Two Micro-DB9 male RS232C serial1
- Micro-DB25 female parallel1
- Micro-DB15 15-pin AUI 10Mbit Ethernet1
- Micro-DB15 VGA graphics1
- Two PS/2 connectors for keyboard & mouse
- Micro-DB9 for audio breakout1
- These micro-connectors need HP conversion cables to provide the normal-sized versions of their respective connectors
ROM update
There is an firmware update available for the 744 VME boards which contains the latest version (4.4).
- PF_C7440044.txt has details about the contents and installation of the patch.
- PF_C7440044 contains the patch.
