Machine translation, like DeepL or Google Translate, is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
Consider adding a topic to this template: there are already 9,119 articles in the main category, and specifying|topic= will aid in categorization.
Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article.
You must provide copyright attribution in the edit summary accompanying your translation by providing an interlanguage link to the source of your translation. A model attribution edit summary is Content in this edit is translated from the existing German Wikipedia article at [[:de:MME U80701]]; see its history for attribution.

U80701FC

The U80701 is a 32-bit microprocessor developed from 1986-1990 in the German Democratic Republic. It was manufactured by VEB Mikroelektronik "Karl Marx" Erfurt (MME) in NMOS technology and is encased in a ceramic quad flat package (CQFP-68 package).^[1]

Microprocessor[edit]

The U80701 was developed by reverse engineering the MicroVAX 78032 microprocessor of the Digital Equipment Corporation (DEC). It is used in the Robotron K 1820 minicomputer - a clone of the DEC MicroVAX II.^[2]

The U80700 system includes the following chips:

U80701: CPU (DC333)
U80703: FPU (DC337)
U80707: Console interface/controller DLART (DC319)
U80709: CPU interface gate array (DC379)
U80711: Q22-Bus interface gate array (DC380)
