Calcorex računski strojček
TRS - Tvornica računskih strojeva Zagreb, Jugoslavija
- Opis:
- Majhen srebrn računski strojček. [SLO]: Prenosni mehanski kalkulator CALCOREX. Prenosni mehanski kalkulator CALCOREX je izdelalo podjetje TRS (Tvornica računskih strojeva Zagreb), jugoslovansko podjetje s sedežem na Hrvaškem. TRS je bil znan po proizvodnji široke palete izdelkov, vključno z merilnimi instrumenti za medicino, kalkulatorji, miniračunalniki, mikroračunalniki, terminali, tiskalniki in drugo računalniško opremo. Čeprav podjetje danes ne obstaja več, je bilo pionir na področju računalništva. Mehanski kalkulatorji so delovali s pomočjo sistema vzvodov, ročic in zobnikov za izvajanje aritmetičnih izračunov. Uporabniki so številke nastavili z drsniki, ki so ustrezali vrednosti mest vsakega števila, in z obračanjem ročice izvajali operacije, kot so seštevanje, odštevanje, množenje ali deljenje. Notranji mehanizem naprave je obračal kolesa številk za prikazal rezultat na vidnem registru. Te naprave so bile pogosto uporabljene v pisarnah za računovodstvo in knjigovodstvo, saj so omogočale ročno, vendar zanesljivo obdelavo zapletenih številskih nalog pred prihodom elektronskih kalkulatorjev. Čeprav mehanski kalkulatorji tehnično niso računalniki, imajo pomembno mesto v zgodovini računalništva. Vsako dejanje, ki ga računalnik izvaja, se na koncu prevede v matematične in logične operacije, naj bo to igranje igre ali ustvarjanje grafike. Kar ločuje računalnike, je njihova sposobnost ocenjevanja pogojev in izvajanja natančnih korakov, znanih kot algoritmi, za izvajanje različnih nalog. Večina zgodnjih kalkulatorjev te sposobnosti ni imela, vendar brez njih računalniška revolucija ne bi bila možna. [ENG]: Portable Mechanical Calculator CALCOREX. The CALCOREX portable mechanical calculator was produced by TRS (Tvornica računskih strojeva Zagreb), a Yugoslav company headquartered in Croatia. TRS was known for manufacturing a wide range of products, including measuring instruments for medicine, calculators, minicomputers, microcomputers, terminals, printers, and other computer equipment. Though the company no longer exists, it was a pioneer in the field of computing. Mechanical calculators operated through a system of levers, cranks, and gears to perform arithmetic calculations. Users would set numbers using sliders corresponding to each digit's place value and turn a crank to execute operations such as addition, subtraction, multiplication, or division. The internal mechanism of the machine would rotate number wheels to display the result on a visible register. These devices were commonly used in offices for accounting and bookkeeping, providing a manual yet reliable means of handling complex numerical tasks before the advent of electronic calculators. While mechanical calculators are not technically computers, they hold an important place in the history of computing. Every action performed on a computer ultimately translates to mathematical and logical operations, whether it's playing a game or creating graphics. What sets computers apart is their ability to assess conditions and execute precise steps, known as algorithms, to perform various tasks. Most early calculators lacked this capability, but without them, the computer revolution would not have been possible.
