Dr. J and Larry Bird Go One on One, more commonly known as One on One, is a 1983 computer basketball game for the early era of home computers. It was developed by Eric Hammond and published by Electronic Arts (EA) and Ariolasoft in Europe.
In this game, the player can assume the role of basketball greats Julius Erving or Larry Bird in a game of one-on-one against another player or the computer. Featuring outstanding animation for its era, the game allows for play to a certain score or timed games. On offense, a player could spin or shoot; on defense, attempt to block or steal the ball, with over aggressiveness penalized by fouls. A hard dunk could shatter the backboard, prompting a janitor to come out and sweep up the shards, directing censored complaints at the player in the process.
One on One originated on the Apple II, but was ported to the IBM PC Jr, Commodore 64, Amiga, Macintosh, Atari 7800, Atari 8-bit, TRS-80 Color Computer and as a PC booter.
