	'''Wire-wrap''' was once a popular technology for production of ~~electronics~~, especially computers. The basic concept is that a series of 'pins' (generally about 2 cm tall, and usually plated in either tin or gold) are connected by wires (usually insulated with Teflon, and stripped about 1 inch at each end) which are wound around the pin, usually by a powered 'gun' (although manual wire-wrap tools do exist). A single pin can usually hold several wires; the exact number depends on the height of the pin, the gauge of the wire, etc.		'''Wire-wrap''' was once a popular technology for production of electronic systems, especially computers.
