=== MARS-1 ===
The [[MARS (ticket reservation system)|MARS-1]] train ticket reservation system was designed and planned in the 1950s by the [[Japanese National Railways]]' R&D Institute, now the [[Railway Technical Research Institute]], with the system eventually being produced by [[Hitachi]] in 1958.<ref name="mars1">[http://museum.ipsj.or.jp/en/computer/dawn/0030.html 【Hitachi and Japanese National Railways】 MARS-1], [[Information Processing Society of Japan]]</ref> It was the world's first seat reservation system for trains.<ref name="dawn">[http://museum.ipsj.or.jp/en/computer/dawn/history.html Early Computers: Brief History], [[Information Processing Society of Japan]]</ref> The MARS-1 was capable of reserving seat positions, and was controlled by a [[transistor computer]] with a [[central processing unit]] and a 400,000-bit magnetic drum memory unit to hold seating files. It used many [[Processor register|registers]], to indicate whether seats in a train were vacant or reserved to accelerate searches of and updates to seat patterns, for communications with terminals, printing reservation notices, and [[Cathode-ray tube|CRT]] displays.<ref name="mars1"/>
