The performanceof "Minsk-23" was about 7 thousand operations per second. Itused many unique at that time, technical developments allowed the machineto work in multitasking mode (advanced system of interruptions and suspensions,universal communication with external devices, a protected area of memory forsystem programs, and others).
The unit could simultaneously be carried out up to 3 workingand 5 service programs. To do this, the machine was equipped with the first"Manager" operating system in the USSR.
Several large Soviet enterprises were based on thecomputer "Minsk-23". The system, for example, used in the Moscowassociation "Mosmoloko", also based on it, built a system for thesale and reservation of "Aeroflot" flight. But commerciallysuccessful "Minsk-23" can not be named - the plant has produced atotal of 28 such machines.
The last of the Mohicans: computer "Minsk 32".
Computer "Minsk-32" was released in 1968 andabsorbed all the best achievements of the previous models in the series.
In addition to substantial productivity gains (the machinepossessed speed about 30 − 35 thousands operations per second), the presence ofa multiprogramming system of work (there could work up to 4 independentchannels at the same time) and the possibility of creating on its basis theMultimachine systems, "Minsk 32" was implemented software compatiblewith previous family computer "Minsk".
In the 60s of the last century, it was a common practice tocreate complex and expensive programs that run only on a single hardware andcomputer system, so that the implementation of such interoperability has becomea real innovation and highlight of "Minsk-32" that this was not ableto offer not only Soviet counterparts, but most of the foreign computers.
From 1968 to 1975, was released about 3 thousand of thesemachines, but, despite this popularity, "Minsk-32" was the lastrepresentative of the whole family of computers "Minsk".
Why computers "Minsk" disappeared
A common problem of all Soviet computers of the late 60-ies(with a few exceptions of "Minsk-32") was a complete hardware andsoftware incompatibility with each other.
Programs designed for a specific computer models simplycould not be used on other machines. This, in turn, significantlyincreased the cost of development, when designers had to "write" aprogram virtually from scratch.
At the same time, the American company IBM didn't wait foranyone and already in 1965 introduced a new, third generation ofelectronic computers on integrated circuits - IBM-360, which were constructiveand the software was fully compatible.
Alas, the second path was chosen, and the development ofcomputer "Minsk" family has been discontinued. In 1970, the foundersof the family of these machines were awarded USSR State Prize, and since 1971the Minsk plant for the production of computers began to produce a computerSingle Series (UCS), the architecture of which was borrowed from IBM.
