Integral

The Integral was HP's first "luggable" computer. It was designed to be transportable, but ran on AC power only. It was the first HP portable/transportable computer to use the HP-UX operating system. The Integral was also the first HP computer to use an electroluminescent screen (orange). The Integral came standard with 512KB RAM, expandable to 2.5 MB. It included a 3.5 inch floppy drive (DS/DD) and a built-in ThinkJet printer.
