4.13 HP 9000/748i & 748 VME Workstations
4.13.1 Overview
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
4.13.2 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.
