4.20 HP Visualize C132L & C160L
4.20.1 Overview
These were entry-level workstations equipped with the low-cost PA-7300LC CPU. They have a similar
case to that of the old 735 — built of interlocking modules so the I/O board, MPU board etc. can be
easily taken out.
Model numbers: both the C132L and C160L have the HP 9000/779 model number.
4.20.2 Internals
CPU
C132L: PA-7300LC 132MHz with 64/64KB on-chip I/D L1 (and 1MB off-chip unified L2) cache
C160L: PA-7300LC 160MHz with 64/64KB on-chip I/D L1 (and 1MB off-chip unified L2) cache
The off-chip L2 cache SRAM is optional and is installed in two DIMM slots below the CPU socket.
The modules must be of equal size. Usually, these systems come with 2 512KB modules, totalling in
1MB L2 cache.
