These HP Visualize J-Class computers were small RISC workstations were aimed at the Unix graphics market, equipped with the new 64-bit PA-8600 and PA-8700, both featuring large on-chip L1 caches. The architecture was a major change from those of its predecessors. New I/O devices were integrated, the LASI I/O chip was removed together with the old GSC bus. All devices now attach to PCI buses, I/O devices are connected to USB ports. The case can be used on the desktop or fitted in a 19″ rack with 2U space.
Model numbers: all have the HP 9000/785 model number.

Chipset
The system is built around the HP Astro chipset:
- HP Astro chipset
- Astro memory and I/O controller connects to the two processors via
the Runway processor bus (2.0 GB/s), the memory bus (2.0 GB/s) and
eight I/O channels (
ropes
— aggregate 2.0 GB/s) and contains both memory, I/O and cache controllers - Four Elroy PCI bridges connect the PCI slots
and I/O devices on the onboard PCI bus to the Astro with an aggregate
bandwidth of 2.0 GB/s on seven I/O channels (one of the eight channels
of the Astro controller is unused)
- PCI 64/66 I/O slot on two channels — 0.5 GB/s
- PCI 64/66 I/O slot on two channels — 0.5 GB/s
- PCI 64/66 I/O slot on two channels — 0.5 GB/s
- Onboard I/O devices (Fast Ethernet, SCSI, audio, IDE/USB etc.) on one channel — 250 MB/s
- Astro memory and I/O controller connects to the two processors via
the Runway processor bus (2.0 GB/s), the memory bus (2.0 GB/s) and
eight I/O channels (
- National 87560 (
Super I/O
), integrates USB, RS232, parallel, floppy and IDE - National 87415 IDE controller
- National USB controller
