Early versions of this keypunch put round holes in 45-column cards. When IBM switched to 80-column cards with rectangular holes in 1928, many machines were reconfigured to the new standard, including this one. The Type 11 was the first electrically-powered IBM punch, which relieved operators from making the punches using muscle power.
