Overview
These HP Visualize B-Class PA-RISC workstations from 2000 were aimed at the graphics workstations market, equipped with the 64-bit PA-8500 or PA-8600 processors with large on-chip L1 caches. The B2000 usually uses the PA-8500 in a small tower case whereas the B2600 is built in a desktop, featuring the PA-8600 CPU. The architecture was a major change from those of its predecessors, the C200 et al, now based on Astro/Elroy, new I/O devices and without the LASI I/O chip and GSC bus. All device I/O now is implemented by PCI buses, human I/O devices are connected to USB ports.
Model numbers: both the B2000 and B2600 have the HP 9000/785 model number.
