HP 9000 Model 320

The HP 9000 Model 320 advanced the Series 300 workstation with a 68020 processor and floating-point coprocessor. It delivered stronger CAD, scientific and software-development performance while preserving DIO peripheral compatibility.

It helped make the 68020-based HP 9000 a significant engineering-workstation platform.

Notable Features

• The 68881 floating-point unit accelerated technical calculations.
• DIO-II increased expansion performance while supporting HP peripherals.

Historical Significance

• It helped make the 68020-based HP 9000 a significant engineering-workstation platform.

Collector’s Notes

• Original HP manuals, peripherals and software media are particularly useful because many interfaces and formats were proprietary.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
