The M1 carbine (formally the United States carbine, caliber .30, M1) is a lightweight semi-automatic carbine chambered in the .30 carbine (7.62×33mm) cartridge that was issued to the U.S. military during World War II, the Korean War, and the Vietnam War. [11]
The most common variant is the IBM Enhanced Keyboard identified by IBM assembly part number 1391401, the U.S. English layout keyboard bundled with the IBM Personal System/2. Until around 1993, most Model Ms included a coiled, detachable cable, with either an AT (pre-1987) or PS/2 connector, in 5- and 10-foot lengths (1.5 and 3 meters).

Therefore, the M1 carbine is significantly less powerful than the M1 Garand. Another comparison is a .357 Magnum cartridge fired from an 18" rifle barrel, which has a muzzle velocity range from about 1,718–2,092 ft/s (524–638 m/s) with energies at 720–1,215 ft⋅lb f (976–1,647 J) for a 110 gr (7.1 g) bullet at the low end and a 125 gr ...

Products, services, and subsidiaries have been offered from International Business Machines (IBM) Corporation and its predecessor corporations since the 1890s. [1] This list comprises those offerings and is eclectic; it includes, for example, the AN/FSQ-7, which was not a product in the sense of offered for sale, but was a product in the sense of manufactured—produced by the labor of IBM.
