Description
The first computer in the Odra series to go into production. Previous models 1001 and 1002 did not receive a satisfactory rating and were not mass produced. Reliability is enhanced by the correct selection of components. In terms of power, the Odra 1003 was five times more efficient than the UMC-1 ; the amount of memory was twice that of its predecessor; the use of electricity was 10 times less, it was also three times lighter in mass and two times smaller in size than the Warsaw predecessor [1] .
In addition to the professional use of a computer for scientific computing, in 1962, engineer Vitold Podgursky from the Elwro factory created a logic game “Marienbad” on the prototype of a computer based on the traditional game “ Nimes ”, a description of which I read in the journal Przekrój . Podgursky programmed for the game all eight kilos of computer memory (almost a billion games each). The computer’s response to the player’s move took a little less than an hour with this setting. It was impossible to defeat the computer even with the standard setting for 16 games. The game algorithm was transferred to the Yaroslav Dombrowski Military Technical Academy ( Polish ) in Warsaw, where volunteers could play against a computer controlled by an operator. University leaders were reluctant to consider using a computer for entertainment [2] .
The surviving copy is an exhibit of the Warsaw Museum of Technology .
