Robotron K 1840
The K 1840, full name RVS K 1840 (, "computer system with virtual memory") is a minicomputer from the German Democratic Republic (GDR). Its development began in August 1985 at VEB Robotron Elektronik in Dresden, and it went into production in 1988. Minicomputer The K 1840 minicomputer is a clone of VAX-11/780 from Digital Equipment Corporation (DEC). The export of western 32-bit minicomputers to Comecon countries was forbidden by the CoCom technology embargo. Therefore one was developed locally, using computer aided design (CAD) technology based on a 32-bit computer architecture. The K 1840 is the first 32-bit computer of the M 32 VAX-compatible minicomputer line. Copies of VAX-11/7xx computers are known also from Czechoslovakia (CM 5152), Hungary (TPA-11/540, 560 and 580), Romania (CORAL 8730) and the Soviet Union (CM 1700). K 1840 has a maximum computing speed of 1.1 MIPS; it can access up to 16 MiB of main memory and up to 4 GiB of virtual memory. The first prototype with the essential core components was introduced in April 1987, and five more were built from then until September 1987. The new computer was presented to the public in October 1987. In 1988 it was awarded the National Prize
