HP Integral PC

The HP Integral PC (or HP 9807A) was a portable UNIX workstation computer system produced by Hewlett-Packard, launched in 1985. It was based on the Motorola 68000 microprocessor (running at 8 MHz) and ran early version of the HP-UX operating system.


The Integral PC was a mains-powered portable computer with a 9-inch amber electroluminescent display with a resolution of 512×255 pixels or 80×24 characters. It also incorporated a 710 kB 3.5" floppy disk drive and an HP ThinkJet ink-jet printer. Standard memory capacity was 256 kB ROM plus 512 kB RAM, expandable to 1.5 MB. Expansion slots and an HP-IB bus were also included.


The Integral PC was unusual in that the HP-UX operating system kernel resided in the ROM, which also included the HP Windows graphical user interface and the Personal Applications Manager (PAM). HP-UX commands and utilities were supplied separately on floppy disk.
