- Calfax
- Description
- This handheld electronic calculator has a plastic case. The oval plastic keys are colored red (the percentage, constant, and clear/clear entry keys), white (the ten digit keys and the decimal point key) and blue (the four function keys and the total key).
- Behind the keyboard is an on/off switch; behind it is an eight-digit red LED display
- A sticker behind the display reads: calfax 890P. A socket for an adapter is on the top edge. This example has no adapter.
- The battery compartment on the top of the back would hold two batteries. This example presently has no batteries. A tag on the back reads: Serial No. (/) 615066 (/) MADE IN HONG KONG.
- The "calfax" mark on the calculator uses a trademark reportedly first used in commerce in 1972, filed in the United States January 1973, and registered in September 1975. No trademark registration is indicated on this example.
- An advertisement in the Washington Post published in July of 1976 shows several Calfax calculators, including a Calfax 890P. It emphasizes the advantage of the percent key. At that time, the model had a sale price of $7.99.
