ILAH Posted June 18, 2022 Share Posted June 18, 2022 I got a CX80 Atari Trackball with the original packing an manual. It has been modded. The JS - TB switch has been removed. Two cables, 1 D-Sub 9 male and 1 D-Sub female leave the case on the left side. The function is like an Atari ST - Mouse and a joytick can be plugged to the second cable an works properly. I took some photos from inside. Was that a common mod by a third party? I would prefer a original behaviour with joystick / trackball mode. Anyone interested in exchanging this one against a CX22 / CX80 or Wico trackball? Quote Link to comment Share on other sites More sharing options...
+x=usr(1536) Posted June 19, 2022 Share Posted June 19, 2022 What's the correct name on the mod PCB? I can make out something that looks like 'Traecase' or 'Raecase' followed by 'Computer' depending on the angle of the photo, but would appreciate a quick clarification. It's an interesting mod, and looks to be fairly easily reversible with the addition of the joystick / trak-ball switch. Quote Link to comment Share on other sites More sharing options...

Fuji-Man Posted June 19, 2022 Share Posted June 19, 2022 I've modded a few CX-80 for Atari ST machines to be used as a trackball. It didn't require that much modding, cutting a trace or two and running a few wires at most. Quote Link to comment Share on other sites More sharing options...

That's true, but the complexity of the mod shown here is due to the inclusion of an automatic switcher to allow a joystick to be left always plugged in the same port. Normally you can't just plug them in parallel - e.g. using a simple Y-cable - as they would interfere with each other. That's what the extra board is for, and I imagine it was taken from a third party switcher, as it seems it has been filed to make it fir inside the trackball case.

ILAH Posted June 20, 2022 Author Share Posted June 20, 2022 Thank you for this information. I will keep the trackball in its actual form. The modification makes scence, and compensates the non original status, i think. Quote Link to comment Share on other sites More sharing options...
