The 4play card is an interface for simultaneously connecting 4 digital (Atari style) joysticks to the Apple II for multi-player gaming and possibly other creative applications. The 4soniq appears to be a 4 channel stereo card.

This is a developing story. More information is forthcoming.

Brisbane, Australia, 29 April, 2016 – Alex Lukacz, well known in Apple ][ circles for his hardware hacking projects, today announced the debut of 4play, a digital joystick interface card for the Apple ][ line of computers. With the 4play card, Apple ][ gamers have a modern solution to connect up to four digital joysticks to an Apple ][.

The 4play supports the original Atari Joystick (and some derivatives of that standard). It is also possible to retrofit 4play support to keyboard-controlled Apple ][ games by redirecting keyboard control calls to the appropriate 4play memory addresses.

The 4play was designed in collaboration with Jesse Blue, of Apple IIgs development powerhouse Ninjaforce. Jesse was instrumental in helping Alex to refine the design and features of the card.

In conjunction with the 4play’s release, Ninjaforce jointly announces a 4play compatible version of its popular Bomberman clone KABOOM! The newly released v1.02 of KABOOM! supports the use of up to four digital joysticks in conjunction with the 4play. Other changes include the ability to control game menus via a connected joystick.

The 4play was announced during the 29 April 2016 WOzFest (Wollstonecraft OzFest) gathering of Apple ][ enthusiasts hosted by Sean “europlus” McNamara on the Lower North Shore of Sydney, Australia. Alex joined the gathering via video hookup to make the announcement, and a pre-release card was available for WOzFest attendees to inspect and use for KABOOM! gameplay.
Technical details on the operation of the 4play and how to modify existing keyboard control code can be found at Alex’s blog. The 4play-compliant version of KABOOM! is available for download from the Ninjaforce website.

Alex Lukacz has been programming Apple ][‘s since 1983, after outgrowing his Dick Smith System80, a TRS-80 Model I clone. After a long hiatus he returned in 2007 to become a regular OzKFest attendee and blogger, showing off various projects ranging from a wireless turtle robot called WALTR to reconstructing Apple ][-driven LEGO kits to his work on floppy drive emulation and video adaptors.

Ninjaforce has long been known for their programming and graphics prowess with their Megademo and work on the Apple IIgs port of Wolfenstein 3D. They literally exploded into prominence on the Apple ][ scene in 2015 with the release of the critically acclaimed Bomberman clone, KABOOM!. KABOOM! pairs exciting gameplay with outstanding graphics and sound to fully exploit the capabilities of the Apple IIgs. Based in Germany, Ninjaforce has released many Apple ][ software products and demos since 1992.
