Casio FX-10 Scientific Calculator
 |
| Brand: |
Casio. |
| Model: |
FX-10 Scientific Calculator. "FX" is the mathematical designation of Function and 10 is for the number of scientific keys of this calculator. |
| Origin: |
Japan. |
| Introduction: |
May 1974. |
| Type: |
Hand-held 10-function scientific calculator operated with 4 AA batteries and external adapter. |
| Functions: |
4 basic functions with constant plus 10 scientific functions: Decimal and Natural Logarithm, e^x, a^n, 1/x, Sin, Cos, Tan, Square Root and Sexagesimal to Decimal conversion.
Also there is a Pi constant key. Please note there is no 10^x key, no inverse trigonometric functions and the a^n key works only with integer values on n between 0 and 9. |
| Display: |
8 digit VFD Digitron display in one crystal tube. Each digit contains 9 segments but this calc uses only 8 segments (7 for numerals plus decimal point). This calc uses the famous "half-height" zero used for Casio in early VFD calculators. The reason for this is unknown, but one possibility is to reduce reading confusion in case of a segment(s) failure. For example, number 1.018046 is displayed as:
|
| Keyboard: |
29 keys in two blocks: 19 colorful big keys for basic functions including Pi Constant and 10 smaller blue keys for scientific functions. On/Off switch. |

Two NEC chips identified as uPD175C (E48076) and uPD179C (E48016) with no identificable datecode. |
