infected Posted May 31, 2009 Share Posted May 31, 2009 Hi! I just bought an Atari 800XL off an Norwegian auction site. What i didn't know was that the atari was modded. Its got a RAM expansion and something other weird stuff. Its a midi/gameport hooked up to some small chips on the main board. I've uploaded some pictures so you guys can have a look and tell me what i've got here and what i can use it for Pics Quote Link to comment Share on other sites More sharing options...
+Guitarman Posted May 31, 2009 Share Posted May 31, 2009 It almost looks like a mod to use a 15 pin PC style joystick on the Atari. Hi! I just bought an Atari 800XL off an Norwegian auction site.

+David_P Posted June 1, 2009 Share Posted June 1, 2009 Might be an add-on to use an XEGS keyboard on an 800xl - tied into the keyboard circuit, I think. Anyone have an XEGS internal show to show how the keyboard is tied in? Quote Link to comment Share on other sites More sharing options...

Anyone have an XEGS internal show to show how the keyboard is tied in? That sound more like it since the gender of the connector is opposite of a joystick.

Rybags Posted June 1, 2009 Share Posted June 1, 2009 The XEGS keyboard has the 2 multiplexor chips inside the keyboard rather than inside the computer. So, a mod for the XL should in theory just connect the cable directly to the relevant Pokey pins, as well as supplying the +5V and Gnd to the connector. Without looking it up properly... I think there should be around 10 wires in use. Quote Link to comment Share on other sites More sharing options...
