In the seventies, large-scale computer dominated, and the data was entered on perforated tape paper. In the early 1970s, Jacek Karpiński wanted to create a compact machine. Model K 202 did not occupy the whole room; it had a monitor and a compatible keyboard. The target was achieved. K 202 weighed 35 kilograms and cost 5 thousand dollars. The machine worked on a 16-bit processor and performed a million operations per second, which is 20 times more than modern Odra at that time.
It might seem that the K 202 and its inventor were facing a great future, the production of prototypes started in 1971. 15 out of 30 copies went to Great Britain; the rest was distributed to national institutions. Unfortunately, as a result of financial problems, K 202 never went into serial production, Jacek Karpiński was removed from work on the computer in general. It was said in those days that if Jacek was born in the USA, his ideas and invention could be the driving force of computer science. Unfortunately, he was born in a socialist Poland, where an understanding for scientists was not fully understood and financed.
