This is set of two Printed Circuit Boards (PCB) modules - 3N1M of first very rare USSR/Soviet/Russian mainframes MIR. This is electronic assembly used as a logic element (AND, OR, NOT, XOR) for first transistorized computer mainframes in USSR (series: MIR-1, MIR-2, MIR-3). The mainframes MIR were made in USSR in 1960's and used programming languages: ALMIR-65 for MIR-1 and MIR-2 and Analitik (Analitik-74) for MIR-3. The machines MIR were a competitor for the well-known American computer "Stretch" (IBM-7030), English transistorized computer "Elliot-803" and the German computer "Siemens-2002". These and similar electronic modules have been working in the Soviet industry on various computer systems until the 1980's.
The electronic circuit has black stamps. The stamps were used in 1960's-1970's time for quality control at the factories USSR. Also on the backside of the circuit board exist seal with month and year of manufacture of the product (for example VII-75). This device was included into main board via PINs (contacts) you can see on the photo 3.
Attention! Location of stamps, number of the stamps on the circuit board, the month and year of the stamps and also 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 it's 40-50 years of storage they look very good. All these rare circuit boards we saved for you and now present them for sale! All devices have fine design and very interesting components on the circuit boards. 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 similar goods, please see our items and write us, we have a lot of different electronic circuit boards from vintage Soviet mainframes. On last photos you can see real Soviet/USSR Computer Mainframes MIR where have been used similar electronic assemblies and circuit boards.
