- Description
- This programmable handheld electronic calculator has a black plastic case and thirty rectangular plastic keys. The model was introduced in July of 1979 and sold through 1983. Most keys take on different meanings if the gold "f" shift key or the blue "g" shift 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. 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 33C.
- 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. (/) 2020S37048. Another mark reads: MADE IN (/) SINGAPORE. The first four digits of the serial number indicate that the calculator was made in the twentieth week of 1980.
- The calculator has a black zippered case.
- 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).
- A December 1980, advertisement lists the price of the calculator as $79.95. Mier-Jedrzejowicz gives a price fluctuating between $120 and $65.
