PHOTO: The Hewlett-Packard Integral PC was developed between 1982 and 1984 in Corvallis, Oregon, including a mouse. The IPC was a sewing machine size "transportable computer" that included a built-in flat panel electroluminescent display, letter size fan-fold paper inkjet printer and it ran the HP-UX UNIX operating system with a graphical windows interface.

My local newspaper printed the AP news story by Michael Liedtke, Associated Press, "Inventor of computer mouse dies at 88," Gazette-Times, July 4, 2013, p. A3, I wrote the following letter to the editor:
Oregon State University alum Doug Engelbart was correctly credited in a July 4 headline written by the Gazette-Times for an Associated Press story, "Inventor of computer mouse dies at 88."
I witnessed firsthand how Apple co-founder Steve Jobs' Macintosh computer mouse was inspired by research, based on Engelbart's ideas, done at the Xerox Palo Alto Research Center and the Corvallis Hewlett-Packard Co. personal computer research lab in 1981.
HP half-heartedly introduced a mouse about the same time Apple did in 1984 because an HP corporate vice-president, unlike Jobs, demanded a touch-screen interface for the sexist reason that only "female secretaries" used typewriter keyboards. Ironically, touch-screen computer interfaces today are rapidly replacing mice for non-sexist reasons!
