||The Integral was a transportable, true multitasking HP-UX UNIX workstation with a real windowing display and a printer built in over the screen.
The Integral was the first major computer with an electroluminescent
display. At 25 pounds and 7 inches by 13 inches by 16 inches, the
Integral was a transportable workstation. (It wasn't truly "portable,"
because it was not able to run off batteries.) Large liquid crystal
displays (LCDs), so common today, did not exist yet, and the electroluminescent
display was expensive and fragile. Introduced as a business computer,
the Integral was expandable up to 5MB RAM.
The Integral was a product of HP's Portable Computer Division in
Corvallis, Oregon. It featured a built-in ThinkJet personal printer,
a full-size keyboard and a 9-inch electroluminescent display that
had "windows" of adjustable size for viewing several different
activities at once. It had a Motorola 68000 16/32-bit processor
and a 16-bit HP graphics processor. The Integral ran HP-UX UNIX.
