HP 9000/745 VME Workstations External connectors
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

One bay for a 3.5″ SCSI drive
