During the Cold War, the concept of the main battle tank was established and guns of 105 mm (4.1 in) (NATO) and 100 mm (3.9 in) (Warsaw Pact) were the standard until the advent of guns of 120 mm (4.7 in) (NATO) and 125 mm (4.9 in) (Warsaw Pact) from the 1960s to the 1990s.
In early 1802-based microcomputers, the companion graphics Video Display Controller chip, RCA CDP1861 (for the NTSC video format, CDP1864 variant for PAL), used the built-in DMA controller to display black and white bitmapped graphics on standard TV screens at up to 64 pixels horizontally by 128 pixels vertically. The 1861 was also known as the ...
Example of a Europlug. The Europlug is a flat, non-rewirable two-pole, round-pin domestic AC power plug, rated for voltages up to 250 V and currents up to 2.5 A. [1] It is a compromise design intended to connect low-power Class II appliances safely to the many different forms of round-pin domestic power socket used across Europe.
The addition is a 3 ⁄ 16-inch (4.8 mm) diameter round or U-shaped ground pin, 1 ⁄ 8 in (3.2 mm) longer than the power blades (so the device is grounded before the power is connected) and located from them by 1 ⁄ 4 in (6.4 mm) edge-to-edge or 15 ⁄ 32 in (11.9 mm) center-to-center.
The .308 Winchester is measured across the grooves and uses a .308-in diameter (7.82-mm) bullet; the military-specification version is known as 7.62 × 51 mm NATO, so called because the bore diameter measured between the lands is 7.62 mm, and the cartridge has a case 51 mm long.
Some railways, primarily in the northeast, used standard gauge of 4 ft 8 + 1 ⁄ 2 in (1,435 mm); others used gauges ranging from 2 ft (610 mm) to 6 ft (1,829 mm). As a general rule, southern railroads were built to one or another broad gauge, mostly 5 ft ( 1,524 mm ), while northern railroads that were not standard-gauge tended to be narrow-gauge.

These run from A to L (omitting F and I) and depending on the largest dimension of the battery can either signify 0.0 – 0.9 mm maximum dimensions or 0.00 – 0.09 mm maximum dimensions with A being 0.0 or 0.00 and L being 0.9 or 0.09.
