Object Details
- Calfax
- Description
- This handheld electronic calculator has a black plastic case. The oval plastic keys are colored red (the clear/clear entry key), white (the ten digit keys and the decimal point key), and blue (the four function keys and the enter key).
- Behind the keyboard is an on/off switch on the right and a D key. Switching the D key changes from floating point arithmetic to a decimal point fixed for dollar and cents results. Behind the switches is six-digit red LED display
- A sticker behind the display reads: calfax 616. There is no socket for an adapter.
- The battery compartment at the top of the back would hold two batteries. This example presently has no batteries. A paper tag within the compartment reads: INSPECTED BY (/) 30 OCT 1975. A paper tag on the back of the calculator reads: Serial No. (/) 479650 (/) MADE IN HONG KONG.
- The calculator fits in a cardboard box with a leaflet of instructions and plastic packing. The "calfax" mark at the top of the instructions and on the lid of the box indicates a registered trademark. This trademark reportedly was first used in commerce in 1972, filed in the United States in January 1973 and registered in September 1975.
- An advertisement in the Washington Post published in July of 1976 shows several Calfax calculators, including a Calfax 616. At that time, the model had a sale price of $5.99.
