HP 9000/748i & 748 VME Workstations
Overview
Project names - uname:
- 748i/64 - Anole-64
- 748i/100 - Anole-100
- 748/132L - Anole-132L
- 748/165L - Anole-165L
The 748i and 748 ruggedized workstations are 743i and 744 VME boards in a heavy, large VME-case, which provides the neccessary I/O facilities:
- Six 6U VME slots for additional I/O boards
- Room for up to four SCSI devices, which can be accessed from the outside
- Four-slot EISA or PCI cage
Internals
CPU
- 748i/64: PA-7100LC 64MHz with 1KB on-chip I L1 and 256KB off-chip unified I/D L1 cache
- 748i/100: PA-7100LC 64MHz with 1KB on-chip I L1 and 256KB off-chip unified I/D L1 cache
- 748/132L: PA-7300LC 132MHz with 64/64KB on-chip I/D L1 cache
- 748/165L: PA-7300LC 165MHz with 64/64KB on-chip I/D L1 and 512KB off-chip unified I/D L2 cache
The 1KB on-chip L1 cache on systems with a PA-7100LC is not really a true 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 ASIC, adds functionality missing in LASI, e.g. HIL, 2nd RS232 …
- WAX EISA bus-adaptor, connects EISA to GSC
- Dino GSC-to-PCI bridge
- 748: Phantom PseudoBC GSC+ port
- 748: Visualize-EG (
Graffiti
) graphics - Intel 82503 Ethernet transceiver, media auto-selection
- CS4215 or AD1849 programmable CODECs
- VME controller
- PCMCIA controller
Buses
- GSC bus
- Optional EISA bus
- Optional PCI-32/33 bus
- VME bus
- SCSI-2 Fast-Narrow single-ended bus
Memory
- Special proprietary ECC mezzanine memory card
- 748i and 748 use different cards
- 748i: Takes 8-64MB special ECC mezzanine cards
- 748: Takes 16-256MB special ECC mezzanine cards
- Up to four cards are supported
- 748i: 8MB minimum, 256MB maximum amount of RAM
- 748: 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) - See GSC/GSC-M expansion cards
- Six 6U VME slots
- Either four EISA or four PCI slots in a separate I/O cage
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
- On configurations with an EISA cage: HIL connector
- These micro-connectors need original HP conversion cables to provide the normal-sized version of their respective connector.
ROM update
There is an firmware update available for the 744-board (used in 748), 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.
