'''ESER''' is an abbreviation for '''Einheitliches System Elektronischer Rechenmaschinen''' ([[German language|German]] for  ''standardized system of electronic computers''), a term used in the [[East Germany|GDR]] for [[ES EVM]] computers produced according to a treaty between the members of [[Comecon]] signed on 23 December 1968 covering the development of a standardized computing system.

ESER was also the name for computers developed by this standard. Most ESER Computers were named ЕС (which is Cyrillic for "ES") followed by a four digit number, e.g., EC 1055, often also called ESER (e.g., ESER 1055). [[VEB Robotron|Robotron]] also produced [[minicomputer]]s, whose names started with "K" (''Kleinrechner'' for "minicomputer").

The ESER systems were in operation in GDR and later in the [[new states of Germany]] until 1995.
