Hewlett-Packard HP 34C Programmable Handheld Electronic Calculator

This programmable handheld electronic calculator has a black plastic case and thirty sloping rectangular plastic keys. The model was introduced in July 1979 and sold through 1983. Most keys take on different meanings if the gold "f" shift key, the blue "g" shift key or the black "h" key is pressed. The calculator has limited programming capabilities. It also has “continuous memory,” which allows limited storage of programs when the calculator is turned off. The calculator featured solve and integrate functions not found on previous calculators.
Behind the keyboard are an on/off switch, a program/run switch, and an LED display. A mark on the front edge reads: hp HEWLETT • PACKARD 34C.
The socket for the battery adapter is along the top edge. The battery compartment is at the top of the back. The back also has four rubber feet. Text on the back reads: SERIAL NO. (/) 2252S33344. Another mark reads: MADE IN (/) SINGAPORE. The first four digits of the serial number indicate that the calculator was made in the 52d week of 1982.
The calculator has a black zippered case with a belt loop. A mark on it reads: hp. It also has a power adapter. A mark on it reads in part: 2213 (/) INPUT (/) 90-120V AC (/) 50-60 HZ (/) HEWLETT-PACKARD (/) 82087B (/) CLASS 2 TRANSFORMER (/) MADE IN SINGAPORE.

This device is part of a series that included the HP-31E, the HP-32E, the HP-33E, the HP-33C, the HP-34C, the HP-37E, the HP-38E and the HP-38C. Compare 1987.0435.09 (an HP-25) and 1987.0435.11 (an HP-33E), and 1987.0435.12 (an HP-33C).
The donor of the calculator, Kim Tracy, purchased it as an engineering student. By this time, he also had access to electronic computers, but used the calculator quite heavily.
