The Arcade Board is a sprite graphics and sound effects board for the Apple II that uses a Texas Instruments TMS9918A video display processor and a General Instruments AY-3-8910 programmable sound generator to generate arcade quality graphics, music, and sound effects. This gave the Apple II graphics and sound capabilities to match those of other 8-bit computers of the time from Texas Instruments, Atari and Commodore.

These added capabilities were accessed through a set of ampersand extensions to Applesoft BASIC called Amparcade.

While the Arcade Board made it possible to write arcade games in Applesoft BASIC, a machine had to be equipped with an Arcade Board in order to run the game. I'm not aware of any software written to take advantage of the board.

The single wire coming from the top right corner of the board connects to the center of the RCA jack video port of the Apple II to provide video passthrough. The top RCA jack is the video output to a composite monitor, and the bottom RCA jack is the monoaural audio output. The 4-pin molex connector between the two RCA jacks is for an RF modulator.[1]

The Arcade Board can be installed in any available slot, but slot 4 or 7 is recommended. To run any of the demo programs on the Amparcade disk the board must be in slot 4.


The Amparcade Diskette contains the Amparcade extensions to Applesoft and several demo programs. This is a ShrinkIt disk archive of a 5.25" DOS 3.3 diskette. [2]
