Object Details
- Hewlett-Packard Company
- Description
- This programmable desktop electronic scientific calculator has a beige metal case, a cathode ray tube display, a keyboard with four groups of keys, and a slot for a magnetic program card. The leftmost set of 15 tan keys includes coordinate conversion, logarithmic, exponential, trigonometric, and absolute value function keys. A switch above it can be set at degrees or radians.
- The set of 15 ivory and dark brown keys second from the left allows for the positioning and storage of numbers in different registers. Next to the right is a set of 20 brown and ivory keys to enter numbers and to specify machine functions. The rightmost set of 14 tan keys is used for programming.
- Five hand-wound circuit boards are inside the case, and three smaller circuit boards are inside the lid. There is a white power cord. A sticker on the back of the machine reads: SERIAL NUMBER (/) 938-02147.
- The Crocker Nuclear Laboratory of the University of California at Davis acquired this machine in May of 1970 for a price of $5,195.00. Funds came from the Atomic Energy Commission’s Experimental Nuclear Physics program.
