The team worked for three years and in 1973 first prototypes were completed. The result was a minicomputer highly innovative in many aspects. K-202 was constructed entirely with microchips, using breakthrough 1971 Intel 4004 chips. It was also asynchronic and used floating point representation, as KAR-65. Moreover, K-202 used memory segmentation with paging, the first minicomputer to do so. Additionally, it performed close to a million operations per second. These two things made K-202 faster than its potentially most dangerous competitors DEC's PDP-11 and CTL's Modular One. The computer was small, could fit on the desk and weighed 35 kilograms. It was also highly shock-, water- and temperature-resistant. K-202 used authorial operation system SOK and dedicated ASSK programming language, but also supported ALGOL 60, FORTRAN IV, BASIC and others. The important feature was also a possibility of accessing up to 64 devices in the same time, hence the high level of freedom of architectural composition of a system.
