|The Hewlett-Packard-75C was Hewlett-Packard's first handheld computer.
Introduced in 1982, the 10-inch by 5-inch by 1-inch HP-75C was
HP's first handheld computer. With 48K ROM and 16K RAM, the
HP-75C ran BASIC and VisiCalc and could be used as a clock and appointment
alarm. It cost $995.
Weighing only 26 ounces, the HP-75 provided 50 functions. It was
an early tool for mobile computing. A repository for field data
that eventually would be transmitted into a host computer, it accommodated
peripherals such as a modem, a digital cassette drive and printer/plotter,
all of which could fit easily into a briefcase. It was aimed at
more technical users than the HP-110 laptop was.
