Atari 8-Player Multijoy Adaptor - new full color assembly instructions

Recommended Posts

Hello Atarians,

Maybe you already know the Atari 8-Player Multijoy Adaptor to play with eight joysticks on one Atari XL/XE Computer.

The plans were quite old, but the german magazine "RETURN" brought a new full color picture assembly instruction in issue #16 - complete with part list, diagrams and photos.

If you ever wanted to build your own Multijoy, this may be of interest:

Greetings

P.S: Building this for your own is legal - even in Europe ;-)

Sadly some sentences must be posted as there are some freaks around want to destroy the scene...

 

This looks like mega fun! Even there are a lot games (in my oppinion) available up to 8 players... Just to find eight in total may in an area like mine really hard :-)

 

Cheers

We met with 4 people in the town called "Essen" and handcrafted the four multijoys pictured above...

You may find some pictures of building the red one here:

@powersoft: Go to the street, collect 7 people and start playing :-)

There should be no problem on events like NOMAM, Fujiama, DoReCo, [Connected], and so on :-)

@8bitjunkie: Where I live are no seven people on the street, haha :-)

 

@kenjennings: I got an idea - but need to check it with two people to make this available...

It's no rocket science, you can build one on a rainy afternoon :-)

That is some serious sorcery. How does it grant the ability to support 8 players? I mean, getting a non 400/800 to support 4-players is impressive enough.

 

I'm assuming it's all due to the POKEY and thus this couldn't be replicated on a 7800.

Hello Lynxpro

 

The Atari can handle 16 players using 16 joysticks via a Multijoy Interface. PIA pins can be switched to output. When using a multijoy interface, one joystick port is switched to output, the other to input. "Input" reads the joystick, "output" selects which joystick is read.

 

Sincerely

 

Mathy
