40pcs VINTAGE MAINFRAME COMPUTER PUNCH CARDS. IBM 80-column card format 70-80s DescriptionColor: creamManufacturer: SoyuzschettehnikaMaterial: paperStandard: TY 57-7-81Application: old USSR mainframes: BESM, MIR, Minsk-32, ES-10XX and othersCondition: new, not used We sell set of 40 pcs cream colored punch cards for vintage USSR Soviet Mainframes in perfect condition (NOS). Many years ago these punch cards were used how information carriers instead of diskette, CD/DVD and Flash drives in Soviet mainframes (series: BESM, MIR, Ural, Kiev, Minsk-32, ES-1060 and others series ES-10XX). These punch cards were created in period 1970’s-1980’s in USSR. Speed of the Soviet punch cards reading depended on the specific implementation of the reader and ranged from 20-50 punch cards/min in the first computers and up to 2000 in newer machines such as the ES-series computers (late 70s). This performance was achieved by using several readers (readers) punch cards in parallel. Information recording (“hole punching”) was performed at the rate of 10-250 punch cards per minute. Soviet punch cards made similar as IBM format and have 80 characters as standard. According to the IBM standard, each card must have size 7⅜ × 3¾ inches (187.325 × 82.55 mm), card thickness 0.007 inches (0.178 mm). Total one punch card can save only 24 machine word. One machine word had a size of 36 bits (in period time when were used the punch cards). Similar punch cards were used for first mainframes in USA (IBM series: 704/709/711/709/7094, American machines UNIVAC) and also for others computing systems. With help these punch cards first programmers wrote first programs using programming languages: Cobol, Algol, Fortran, Assembler and others. We even saw the first games for mainframe developed with help Fortran and similar punch cards about 20 years ago. Interesting facts: According to approximate calculations, a Gigabyte of information presented in the form of punch cards would weigh about 22 tons or if you add all the punch cards to one another, this stack would be about 2 km tall. Surprisingly, punch cards are still used on old computers in Russia, Ukraine and some other republics of the former USSR at the old factories! This is the last memories of the past era of vintage Computing Technologies and Computing Machinery! This can be very good souvenir and surprise for fans of computer technology. Very good use of these cards for notes and bookmarks -)). See also additional photos where you can see applying these punch cards in the Soviet industry and in the world. In these photos you can see equipment for work with these punch cards in period 1970-1980s. We have a small amount of punch cards. With each new sale amount of punch cards decreases and the price can rise. 100% Genuine Soviet items 30 days returned accepted Fast handling Safe and careful packaging Combined shipping 100% Genuine Soviet items 30 days returned accepted Fast handling Safe and careful packaging Combined shipping 100% Genuine Soviet items 30 days returned accepted Fast handling Safe and careful packaging Combined shipping Photos100pcs Vintage Mainframe Computer Punch Cards.
