We go through the instruments
The IT DataArt Museum has been around for seven years. It began with an attempt to save that little that still remained for experienced programmers from their creative IT youth. Colleagues began to bring their own relics: entire computers and old processors, modems, huge floppy disks and mice, boards of still Soviet PCs, phones and pagers. Now there are several dozens of exhibits in the windows of the museum at the development centers in St. Petersburg and Voronezh, and this year DataArt released a special series of posters with some of them.
Hard Drive MS-5401
The first version of the HDD-MS-5401 since 1986 was produced at the Gorky Design Bureau of NIITOP, specializing in the cloning of Western electronics. The original for it was the Seagate ST 506. The DataArt Museum presents the second version of the MS-5401 HDD, such hard drives have been produced in Rostov-on-Don and Kiev since 1987. Unformatted disk capacity - 6 MB. It was used, for example, in the Electronics-85 PC.
8 bit punched tape
Paper punched tapes have been used in computer technology since the 1950s. By the 1980s, their field of application narrowed mainly to numerically controlled machines and stand-alone devices: paper tape is in many ways more reliable than magnetic media. A copy from the DataArt collection - 1983. It contained the image of the ROM firmware for a military on-board computer.
Digital PDP 11/34 ADM3A minicomputer
video terminal DEC-compatible video terminal was manufactured by Lear Siegler since 1976 and was sold at a low price of $ 1195 by then standards. Escape sequences first implemented in ADM3A are still alive. Say, to move the cursor around the screen, the HJKL buttons were used there along with the Ctrl button pressed - this is still supported in the vi editor.
QuickShot is the world's first ergonomic joystick. In 1982, they came up with Spectrvideo. QuickShot allowed you to play games on computers and game consoles Atari, Commodore, MSX, Amiga, Amstrad, Nintendo and Sega. The QS-113 model from the DataArt collection is one of the simplest. She allowed to play on IBM PC / XT.
The arithmetic line produced by the Leningrad Severny Press plant is the Soviet version of the Kummer calculator. The numerator was invented in 1846 by the St. Petersburg music teacher Heinrich Kummer and in different versions was released until the end of the 1970s. The ruler is built on the principle of abacus and allows addition and subtraction by sequential actions. The stylus stick is needed in order to collect numbers in each category. The upper black lever is a reset.
A rather rare clone of the 8-bit English ZX Spectrum 48K has been produced since 1991 by the Component Leningrad plant. Almost completely compatible with the original, despite the circuitry differences. Instead of the original Zilog Z80 with an operating frequency of 3.5 MHz, the domestic T34VM1 microprocessor is installed in the PC. On Spectrum, most of the games for Spectrum were launched.
The training stand based on the K580IK80 microprocessor The K580IK80
microprocessor is a functional analog of Intel i8080 with a clock frequency of 2 MHz. It was produced since 1977. The copy stored in the DataArt collection was used at the Leningrad Institute of Precision Mechanics and Optics (LITMO) to educate students in the specialty of computer technology.
KL-1 circular slide rule
Like an ordinary flat, circular logarithmic ruler, it allowed to perform many mathematical operations: multiplication, division, squaring, square root extraction, calculation of direct and inverse trigonometric functions, and so on, while being compact. The model was produced for several decades by the Moscow Experimental Control Instrumentation Plant Kontrolpribor.
Yamaha YIS503III KUVT-2
The student’s workplace as part of a set of educational computer technology (KUVT) based on household Yamaha MSX standard 8-bit computers. Similar kits were used in the educational process of schools in the USSR from the mid-1980s to the beginning of the 1990s. The computers used as part of the kits were adapted serial models: their keyboard and software were Russified.
The smallest and cheapest of electromechanical arithmometers weighing 3.5 kg was produced from the 1960s to the 1970s. He performed four arithmetic operations. A clone of a similar German device Contex 20.
RL01 K-DC disk package for minicomputer manufactured by Digital Equipment Corporation (DEC) PDP 11/34
PDP-11 is a family of 16-bit minicomputers, various models of which were produced from the 1970s to the 1990s. For PDP-11, several disk pack models were released. The 19-inch RL01 model contained 5 MB of data, and to read it, a 34 kg drive was needed. Another RL02 drive model contained 10 MB.
Motorola TeleTAC 250
Motorola launched its MicroTAC series of phones in 1989. Then they were the lightest phones on the market, and thanks to this, they became one of the most popular, despite the fact that they were sold for $ 2500-3500. The TeleTAC 250 model was produced since 1994 and differed from the previous ones in that it did not have a “flip” - a cover that closes the keyboard. The phone worked on first-generation (1G) analog cellular networks.
