We sell set of two Printed Circuit Boards (PCB) modules - M2M-1 of first very rare USSR/Soviet/Russia mainframes MIR. Every module has size 5.3 x 3.3 cm. This is electronic assembly used as a logic element (AND, OR, NOT) for first transistorized computer mainframes in USSR (series: MIR-1, MIR-2, MIR-3). In USSR during the 1960s for machines MIR used programming language Analitik (Analitik-74) and the machines MIR were a competitor for the well-known American computer \"Stretch\" (IBM-7030), English transistorized computer \"Elliot-803\" and the German computer \"Simens-2002\". We sell the two same modules M2M-1 with a few differences. These and similar electronic assemblies have been working in the USSR industry on various computer systems until the 1980s. Below you can see pictures of these first mainframes. The electronic circuit has black stamps print. The stamp print was used in 60-70s time for quality control at the factories USSR. Also on the back side of the circuit board exist seal - the month and year of manufacture of the product (for example VII-75). This device was included into mainboard via PIN contacts or connectors (see photo 3). The photo of the PIN contacts only for understanding what it is (it is photo of the similar circuit board). All PIN contacts are same for all PCB of the series mainframes MIR that we sell. Attention! Location of stamp print, number of the stamps on the board, the month and year of the stamps, color of the board may vary. Labels and color electronic components mounted on the board may also vary slightly. We have a number of very similar types that have small differences (year, a slight difference in shades of parts, etc.). These printed circuit boards were stored for a long time in an old warehouse in boxes and may have minor damage from time, but for its 40 years of storage they look very good. These unique circuit boards were not injured by a fluke and now presented for sale! All devices have fine PCB design, layout and very interesting circuit board components. You have a chance to get these unique devices. This can be a very good gift for anyone who has an interest in computer science or electronics, or just people who like IT. If you have interest to same goods, please write us, we have a lot of different electronic circuits and circuit boards from old USSR mainframes. You can see gallery for reviewing other similar models. Also on last photos you can see real Soviet/USSR Computer Mainframes MIR where have been used similar electronic assemblies and printed circuit boards. Please, see all photos! Small pictures are clickable and can be enlarged for viewing.
