"Och", the first microcomputer assembled and put into operation in Mongolia, turned 38 today / May 17, 2022 /. The computer was first tested on May 17, 1984, by members of the Central Science and Technology Council of the Central Statistics Office. It has been 38 years since the official letter No. 4/5 “Application” was delivered to the State Committee for Science and Technology, which was signed by Luvsandorj, Chairman of the General Counsel. In the Application, it said that “After studying the optimal proposal material called “Och”, a micro-computing electronic machine developed by the engineers of the Computing Center of the Department O.Batsukh, G.Oyunbayar and D.Tolya. Dashtseren, Myagmarsuren, L.Gantulga, a teacher at the Young Technicians' Palace, and A.Gantumur, an engineer at the UAMD Institute, it is proposed to discuss it with the board of the State Committee for Science and Technology, approve it and issue a certificate to its creators. Please study the relevant materials and make the appropriate decision.” Since then, there is a possibility of Flame and Fire from “Och”, but the ignition is low. Congratulations on the 38th anniversary of the creation of "Och" to the families, relatives and friends of our friends who went to heaven and wish them all the best! The microcomputer "Och" used a small TV called "Youth" instead of a display, and instead of an HDD used a recording player called "Electronics" and a magnetic cassette. The base of the chips was sawn by IBM mainframe connectors. Power supply not saved. The Och computer is now housed in the Museum of National Information Technology Park. For 38 years, after the commissioning of Och, O. Batsukh, who went to Moscow to study for a postgraduate degree and received a doctorate, and Myagmarsuren, a designer-teacher at Young Technicians' Palace and later became a leading car paint service provider, have gone to heaven. Rest in peace. Dashtseren, a former engineer of the Ministry of Defense, risked his life to participate in the first hunger strike in 1990 to start democracy in order to computerize the country, and is now a businessman. Engineer D. Tolya and author himself went to the United States on a green card after assembling and commissioning Mongolia's first supercomputer, Bit HPC, in 2006. He is now a local citizen and works for a branch of Siemens. Engineer A.Gantumur, who provided many small capacitors and elements and supported them with tools, established “Khet Motors” LLC to diagnose and repair motors and cars. L. Gantulga, a handicraft teacher, still works in the education sector and has many students. We pay tribute to the memory of Sh. Sodnomdarjaa, the former head of the Young Technicians' Palace, who approved the installation of this computer! I am grateful to D.Tsetsegmaa, a teacher who used her electronics laboratory 24/7 for 2 months. Good health to the Computing Center engineers who replaced our work while working at Young Technicians' Palace! We are also grateful to Sister Donjoo and Brother Maam, the engineers and designers of the Computing Center, who provided us with an eraser and a programmer to type the system on the regular memory chip 2716.
WHAT ARE THE FEATURES OF OCH?
It was small in size, inexpensive (~ USD500), relatively high in capacity * (intel8080), large in RAM * (16KB), easy to use, but very reliable. The comparative computer was a 22-seat MERA-100 (USD15000) mini-computer installed in 1983 in the provincial capital, the Statistical Office of three cities, and the Computing Center. Mainframe Minsk-32 took 90 sq m, IBM360 took 110 sq m spaces. However, the MERA-100 only allowed assembly language, and in addition to the "Och" assembler, it was a compact desktop computer with BASIC, which did not require high user programming skills. One problem was that the chips used to build the Och were mostly from Intel, so they weren't in our store, not even in the Soviet Union, Germany or Poland. It was on the black market in Hungary and Poland. When the Soviet Union invaded Afghanistan in 1979, a number of countries, including the United States, imposed the sanctions on the Soviet Union, including the People's Republic of Mongolia until 1989. Och's chips and parts were collected for three years through the purchase of spare parts from German and Hungarian equipment, the exchange of goods with Polish experts, and the secret purchase. Although Och won a bronze medal at the biennial Innovation-84 exhibition, the SOCOM representative in Mongolia did not speak out. At the time, Sanction’s envoy was the Secretary of the Embassy of the United Kingdom of Great Britain and Northern Ireland. In the processor box of the "Och", a plate with serial data chip 8251 was assembled to connect the modem and transmit data over the telephone line, and a 25-foot connector was screwed on the outside.
DID THE CREATORS 'GOALS COME TRUE?
Like the IBM PC and Apple II, which were just being introduced at the time, the Och was designed to be used by every professional, as a home computer, and to connect to a network. To date, PCs have not reached every household in Mongolia, but there are many assemblers, wholesale suppliers, and Och has reached the level of Flame. In terms of network, PCs in central urban areas and enterprises are connected to fiber-optic networks, but fixed data services are very inadequate in suburban ger areas. Although mobile data services have reached Ulaanbaatar's ger districts, aimags, soum centers, and settlements, they have reached only a small part of herder cities and pastures, it is too small number for a neighboring country of China, the world's largest producer of telecommunications and electronics. D.Enkhbat (a candidate for President of Mongolia last year), a programmer who worked with us at the Computing Center, took the initiative to connect Mongolia to the Internet in 1996 at his own expense. Today, more than 30,000 km of fiber-optic cables with a capacity of hundreds of terabit/s have been laid in rural areas, and thousands of stations capable of providing wireless data services at tens of hundreds of mbps have been installed. More than 80% of the land is inaccessible to data services, and rural herders have access to winter camps, summer camps and pastures, although they have high-capacity processors, multiple gigabytes of memory, smart devices with 3G / 4G / 5G modems, and no internet. What is the main cause? Our fiber optic tariffs are very high, for example, 1Mbit/s from UB to the United States is ₮ 16,000 (Gemnet LLC), and from UB to aimags and soums, and from Central Post Office to UB ger districts is ₮ 80,000 (ICN SOE). In rural areas of Latvia, Estonia and Kazakhstan, as well as in the United States, Japan and Germany, the monthly tariff per 1 mb/s is less than $ 1. In terms of PC penetration, the goal of "Och" was close to being achieved, and with the help of smart devices, it became "Fire". As for the data transmission network, high-performance transmission and termination devices and stations were installed along the settlements and roads in Mongolia. However, even 1% of the fiber-optic capacity of soums and settlements is not used, while the service tariffs for rural residents are high but service is low. In herders' pastures and winter camps, even though they have smart devices, they do not receive landline or cellular signals, or “fire” lacks the fuel. In 1984, the sanction was the main obstacle to the mass production of computers, but today the Parliament is playing the role of sanction, which does not change the provisions of the law that set very high tariffs for local transmission. Today's “New Och seems to be that the Ministry of Digital Development and Communications and the Government will develop a well-founded proposal and submit it to the Parliament. Enjoy it as a Flame and then as a Fire, it will enhance the development of Mongolia and good luck!
