Overview

These HP Visualize B-Class and C-Class PA-RISC workstations were aimed at the graphics workstations market, equipped with 64-bit PA-8500 processors featuring large on-chip L1 caches. Still part of the HP 9000 range of Unix PA-RISC workstations, they were sold in the late 1990s to early 2000s, and were some of the last PA-RISC desktop workstations.

The C3600 is essentially a C3000 upgraded to a PA-8600 CPU, the C3700 is the same, but upgraded to a PA-8700 CPU. There were additionally various more upgraded models, e.g., the C3650 and the C3750, the former with a faster PA-8700 CPU, the latter with an even faster PA-8700+ CPU. The architecture was a major change from its predecessors with new I/O devices integrated and the LASI I/O chip removed together with the GSC bus. All device I/O is attached to PCI buses, external I/O devices are connected to USB ports.

Model numbers:

B1000 and all C3x00/C3x50 have the 9000/785 model number
