Minsk family of computers

Minsk family of mainframe computers was developed and produced in the Byelorussian SSR from 1959 to 1975.

The most advanced model was Minsk-32, developed in 1968. It supported COBOL, FORTRAN and ALGAMS (a version of ALGOL). This and earlier versions also used a machine-oriented language called AKI (AvtoKod "Inzhener", i.e., "Engineer's Autocode"). It stood somewhere between the native assembly language SSK (Sistema Simvolicheskogo Kodirovaniya, or "System of symbolic coding") and higher-level languages, like FORTRAN.

At one point Minsk-222 (an upgraded prototype based on the most popular model, Minsk-22) and Minsk-32 were considered as a potential base for a future unified line of mutually compatible mainframes — that would later become the ES EVM line, but despite being popular among users, good match between their tech and Soviet tech base and familiarity to both programmers and technicians lost to the proposal to copy the IBM/360 line of mainframes — the possibility to just copy all the software existing for it was deemed more important.

M-20 (Michigan highway)

M-20 is a state trunkline highway in the US state of Michigan that runs from New Era to Midland. It crosses through rural Lower Peninsula forest land between the two ends. The highway serves the college towns of Big Rapids and Mt. Pleasant, home of the main campuses of Ferris State University and Central Michigan University, both located near the trunkline.

Originally in July 1919, M-20 was routed farther north along a corridor now used by US Highway 10 (US 10). The M-20 designation was shifted south to the corridor it now follows. It previously connected to Bay City, and in 1958, a freeway was opened from Bay City to Midland. The former M-20 along Midland Road, going through Auburn, was returned to local control at that time. In 1960, the M-20 freeway became US 10, moving M-20's terminus to Midland. Prior to 1969, M-20 extended on the west end to Muskegon before it was rerouted from White Cloud to New Era.
