Quite cheerful colour scheme. One of two calculators to say they are a Texet 880. The on/off switch on the right hand side, midway, is down for on, which is confusing. Buttons make a hollow clicking sound. This example still has the plastic covering the aluminium panels. |

| Logic comments: | The (CE) button is used to clear last entry of a number and (C) to clear the whole calculator. (CA) appears to clear all, even the memory. |
| Overflow on number input is suppressed, typing in a nine digit number ignores the ninth digit. | |
| An overflow error is not flagged you just carry on! | |
| Divide by zero results in a "00000000" (with no decimal point). Calculation can continue another divider. | |
| There is no constant on any functions | |
| There is no indication of memory store - you have to remember it. | |
| Negative numbers are flagged by a "-" sign in the immediate left digit, limiting you to seven digit negative numbers. |

Measuring 145mm by 80mm by 33mm
this bold yellow and black Texet box stands out in a shop display very
well. Not much bigger than the calculator means there were few
extras sold with this.
The Model number "Texet 880" is a sticker, so this box covered more than one model. Made in Hong Kong There is also a basic instruction manual, 4pp black only named 880A Instruction Manual. It is 130mm by 64mm |
