HP Integral PC

The Integral PC was a transportable Unix workstation with a folding keyboard and a sharp electroluminescent display. HP-UX and a graphical environment were stored in ROM, allowing the system to start quickly from floppy storage.

It placed a complete 68000 Unix development environment in a portable package years before Unix laptops became practical.

Notable Features

• HP-UX and the Personal Applications Manager were resident in ROM.
• The electroluminescent display provided exceptional contrast but no colour.

Historical Significance

• It placed a complete 68000 Unix development environment in a portable package years before Unix laptops became practical.

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.
