''Anti-Aircraft'' is a two-player arcade game by Atari, Inc, originally released in 1975. The game is sometimes referred to as ''Anti-Aircraft II'', denoting the two-player aspect of the game.〔 (【引用サイトリンク】 url=http://www.klov.com/game_detail.php?game_id=6892 )〕 ==Technology== The game is housed in a custom cabinet that includes two sets (one set per player) of three control buttons (up, down, and fire). The game PCB is composed of discrete technology with game sprites stored in ROM. There is an undocumented option available that switches the planes into UFOs. Pin 14 of the 003127 IC — a PROM located at grid location K1 — is tied to ground, but also has a pullup resistor. Cutting the ground trace causes address bit A4 to be pulled high, selecting the UFO data. A jumper can be installed to easily switch back and forth between planes and UFOs.〔 The vertically set monitor is a black and white Motorola XM501.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Anti-Aircraft (video game)」の詳細全文を読む スポンサード リンク
