1) These are classic representatives of calculators for high-paying consumers of the early 90`s: hp-48gx(~$1000)/ti-85(~$550). Approximate retail prices are given in the modern equivalent for 1993. For such a price, the manufacturer did not spare the paint for the letterings.

2) ti-85/fx-2.0. In 1999, CASIO released the fx-2.0 model(~$300 in modern equivalent). Note the size of the labels for x^2, 10^x and e^x on the left and right. This extravagance on the right did not extend further to arcsin, arccos etc. But in general, the inscriptions are quite satisfactory.

3) fx-2.0/graph25 from CASIO. The quality of the paint above the keys in graph25 is slightly better than in fx-2.0. However, to compensate for the cost, the letterings are either thinner or smaller. Visual perception has deteriorated.

4) graph25/fx-9850gb+. It seems that the price of paint exceeds the price of gold. According to some distributors, modern buyers can`t afford an extra $1 for the beauty in one calculator, so here we see another masterpiece of design thought.

5) ti-83+/ti-83+SE. Texas Instruments took care too of low-income engineers and students, saving on design. In the "Silver Edition"(sic!) the LCD was also "optimized" (by reducing its quality).

6) fx-991 classwiz(brand new)/(used). After several months of using the device in the production room and after a dozen wipes with a dry cloth from dirt, the inscriptions above the keys became unreadable. And then my talent as a graphic designer was awakened ...
