<h1>Texet 880 Executive (1977-78)</h1>
|
|
<p>The calculator measures 74.2mm x 135mm x 22.2mm. It weighs 86g without the battery installed, which is a 9v PP3-type battery. Rather than the usual press-stud type holder, the housing has two metal slide clips. There is also what I assume to be a sponge at one end which is supposed to aid in holding the battery in, however it appears to have gone completely hard and I will most likely replace it in the future. There's small adaptor hole at the top, of which the input isn't specified (though it's generally agreed that it's 4.5v centre-positive).</p>
|
|
<p>The case is black & silvery colored with a thin brushed metallic front panel. The eight-digit bubble display has an absolutely <i>terrible</i> viewing angle, which means you either have to be holding it under your coat or against your face to read it!</p>
|
|
The keypad is particularly strange in the way that it has 3 cancel buttons, <pre>[CE]</pre>, <pre>[C]</pre> and <pre>[CA]</pre>, while the <pre>[CS]</pre> button is a Clear Sign button, <i>not</i> another cancel! The keys themselves are particularly stiff, and you really have to push them to get them to register. Many 880s suffered something referred to as the "pseudo fixed decimal bug" where, if you typed in <pre>1 + 1.00 = </pre>, it would display <pre>2.00</pre> instead of the expected <pre>2</pre>
