Original equipment manufacturer (OEM) is a company that makes a part or subsystem that is used in another company's end product. For example, if Acme Manufacturing Co. makes power cords that are used on IBM computers, Acme is the OEM.

However, the term is used in several other ways, which causes ambiguity. It sometimes refers to the maker of a system that includes other companies' subsystems, an end-product producer, an automotive part that is manufactured by the same company that produced the original part used in the automobile's assembly, or a value-added reseller.

Automotive parts

When referring to auto parts, OEM refers to parts and manufacturers involved in the final assembly of a vehicle—in contrast to aftermarket parts that can be installed after the car comes out of the factory. For example, if Ford used Autolite spark plugs, Exide batteries, Bosch fuel injectors, and Ford's own engine blocks and heads when building a car, then car restorers and collectors consider all of those brands as OEM brands, in contrast to aftermarket brands (such as Champion plugs, DieHard batteries, Kinsler fuel injectors, and BMP engine blocks and heads). This can mean that Bosch injectors, for example, are considered OEM parts on one car model and aftermarket parts on another model.

OEM is an original equipment manufacturer, the original manufacturer of a component for a product, which may be resold by another company.

Code page 866 (CP 866) is a code page used under MS-DOS to write Cyrillic script. It is based on the "alternative character set" of GOST 19768-87. The code was widely used during the MS-DOS era because it preserves the pseudographic symbols (unlike Windows-1251) and maintains alphabetical order (although non-contiguously) of Cyrillic letters (unlike KOI8-R).

Code page layout

Each character is shown with its equivalent Unicode code point and its decimal code point. Only the second half of the table (code points 128–255) is shown, the first half (code points 0–127) being the same as ASCII.

Code page 808

IBM code page 808 is a variant of code page 866; the only difference is the euro sign (€) in position FD_hex (253).

Code page 900

Before Microsoft's final code page for Russian MS-DOS 4.01 was registered with IBM by Franz Rau of Microsoft as CP866 in January 1990, draft versions of it developed by Yuri Starikov (Юрий Стариков) of Dialogue were still called code page 900 internally. While the documentation was corrected to reflect the new name before the release of the product, sketches of earlier draft versions still named code page 900 and without Ukrainian and Belarusian letters, which had been added in autumn 1989, were published in the Russian press in 1990.
