КР1858ВМ1
The U880 is an 8-bit microprocessor that was manufactured by Volkseigener Betrieb, VEB Mikroelektronik "Karl Marx" Erfurt (abbreviated as MME; part of Kombinat Mikroelektronik Erfurt) in the German Democratic Republic. Production of the U880 started in 1980 at VEB Funkwerk Erfurt (abbreviated as FWE; the plant was renamed to VEB Mikroelektronik "Karl Marx" in 1983). The U880 is an unlicensed Clone (computing), clone of the Zilog Z80 microprocessor, also supporting illegal opcodes and bug compatibility, bugs, except for very minor differences like not setting the CY flag for the command (when L goes zero). Processor variants The U880 was manufactured in NMOS logic, NMOS technology and encased in a plastic Dual in-line package, DIL40 package with a pin spacing of 2.5 mm (export versions had the Western pin spacing of 2.54 mm; #Further development, Russian variants also came in a ceramic package). The military version of the U880 has an additional "MEK 4" marking. Im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zilog Z80
The Zilog Z80 is an 8-bit computing, 8-bit microprocessor designed by Zilog that played an important role in the evolution of early personal computing. Launched in 1976, it was designed to be Backward compatibility, software-compatible with the Intel 8080, offering a compelling alternative due to its better Integrated circuit, integration and increased performance. Along with the 8080's seven Processor register, registers and flags register, the Z80 introduced an alternate register set, two 16-bit index registers, and additional instructions, including bit manipulation and block copy/search. Originally intended for use in embedded systems like the 8080, the Z80's combination of compatibility, affordability, and superior performance led to widespread adoption in video game systems and home computers throughout the late 1970s and early 1980s, helping to fuel the personal computing revolution. The Z80 was used in iconic products such as the Osborne 1, TRS-80, Radio Shack TRS-80, Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MME U82720DC03 (=i82720)
Madam (), or madame ( or ), is a polite and formal form of address for women in the English language, often contracted to ma'am (pronounced in American English and this way but also in British English). The term derives from the French , from "" meaning "my lady"''.'' In French, the abbreviation is "" or "" and the plural is (abbreviated "" or ""). These terms ultimately derive from the Latin , meaning "mistress". Use as a form of address Formal protocol After addressing her as "Your Majesty" once, it is correct to address the Queen of the United Kingdom as "Ma'am" with the British short pronunciation (rhyming with "jam") for the remainder of a conversation. A letter to the Queen may begin with ''Madam'' or ''May it please Your Majesty''. Other female members of the British royal family are usually addressed in conversation first as ''Your Royal Highness'' and subsequently as ''Ma'am''. ''Madam President'' or ''Madame President'' is a formal form of address for female presiden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VEB Polytechnik
VEB Polytechnik was a company from the German Democratic Republic (GDR) located in Chemnitz (then called Karl-Marx-Stadt). In the GDR, it was mainly known for producing overhead projector An overhead projector (often abbreviated to OHP), like a Movie projector, film or slide projector, uses light to Projector, project an enlarged image on a Projection screen, screen, allowing the view of a small document or picture to be shared ...s, called Polylux. The company was founded in 1870 as ''Reißzeugrichter'' and manufactured drawing table tools. In 1874 the founder Emil Oskar Richter invented the bow compass. After switching its focus to overhead projectors in the late 1960s, it was renamed to VEB Polytechnik. After the collapse of the GDR, the remains of VEB Polytechnik were rescued in a new company called Polytechnik Frankenberg GmbH. It produced overhead projectors and hand lever cutting machines. The new company was closed in 2006. In 1983, the company started manufacturin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poly Play
''Poly-Play'' is an arcade cabinet developed in East Germany in 1985 in video gaming, 1985; it is the only such machine to originate in the GDR. It was created by VEB Polytechnik and contained a number of games, including a ''Pac-Man'' clone. A total of about 2,000 units of the cabinet were manufactured. Hardware ''Poly-Play'' ran on a U880, a clone of the Zilog Z80 Central processing unit, CPU, which was clocked at 2.457600 Hertz, MHz and a custom sound chip. Its display ran at a resolution of 512*256 at 50 Hertz, Hz and supported a palette of ten colours, though it could also use coloured overlays. The machine's coin slot was designed for 50 Pfennig, but it was flawed - the pressure sensor could be deceived by pressing a 1-Pfennig coin very sharply into the top of the slot. However, this was largely tolerated because the machine was not a Capitalism, capitalistic commercial venture, but a state-owned product found predominantly in Free German Trade Union Federation, FDGB hol ...

LC80
The educational computer LC80 was a single-board computer manufactured in the German Democratic Republic (GDR) and intended for teaching purposes. It was the first computer that retail customers could buy in the GDR. History and development The development of the LC 80 started in 1983. At the Leipzig Trade Fair in the spring of 1984 it was presented to the public. Early in 1985 the LC80 was on the market, making it the first computer available to retail customers in the GDR. The computers Z 9001 and HC 900 that had been shown at the same spring fair, could not be manufactured in sufficient quantity and were thus available only to educational institutions. The production probably ended around 1986/87. Technical details The LC80 was programmed by entering hexadecimal machine codes via a built-in 25-key calculator keyboard (16 hexadecimal keys, 7 function keys, NMI, Reset). Programs could be saved and loaded via cassette tape or EPROM. Beside the CPU the board contained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robotron Z1013
The MRB Z 1013 () was an East Germany, East German single-board computer produced by VEB Robotron Riesa, which was primarily intended for private use and educational institutions. It was powered by a U880 processor (a Zilog Z80, Z80 clone) and sold together with a membrane keyboard, membrane (flat foil) keyboard. Initially, the kit was equipped with 16 kilobytes of DRAM, which was later replaced by a 64 KB version. The kits first became available for sale in 1985 and were distributed in a unique way at the time. To purchase it, buyers had to send a postcard to the Robotron shop in Erfurt and wait six to twelve months and then to pick the kits up in person. The package contained the assembled and tested motherboard, a membrane keyboard, various small parts and detailed technical documentation. This basic kit was shipped without power supply or casing for the Printed circuit board, PCB. Most users tended to program the kit using the BASIC interpreter, which was loadable from compac ...
