HP A4978A, J5000 Visualize Workstation, Dual 440MHz Processors, 512MB RAM, B123L+, HP A4978A

These HP Visualize J-Class workstations were aimed at the graphics workstations market, equipped with up to two 64-bit PA-8500 processors with large on-chip L1 caches. They are basically the bigger brothers of the C3000/C3600 et al, featuring better expandability. The architecture was a major change from its predecessors with new I/O devices and no LASI I/O chip or GSC bus anymore. All device I/O now attach to PCI buses, external I/O devices are connected to USB ports.
