Many people contact me for information about various calculators they have in their drawer. The most important indicator for the collective value is first of all the way in which the figures are displayed. LED (lights, which are therefore also visible in the dark) calculators are usually older and more collectible than calculators with LCD . There are also some subtle exceptions, I will write a few more notes about that.

Hello Eric,

If I am correct, the early electronic (office) machines with the real counting tubes (Nixie) are generally the most collectible, apart from exotic hand machines, such as the Liechtenstein drum. whose name I lost (I'm not a calculator collector, sorry)

Greetings,

Leon
