foxtrot Posted April 27, 2016 Share Posted April 27, 2016 Are there any proven work-arounds/hw mods for the weak joystick port? I remember reading something here a long time ago about not enough current and the alpha-lock key but can't recall the details.. The joystick doesn't seem to respond at times, I seem to recall having this issue back in 1982 when my parents bought the ti99 for us. So this isn't an age related issue and is probably an inherent design issue. Quote Link to comment Share on other sites More sharing options...
+arcadeshopper Posted April 27, 2016 Share Posted April 27, 2016 First off, be sure you are using the joystick port and not the cassette port it's the one on the left side.. the cassette is on the back Second are you using the TI joysticks? or an adapter and atari-compatible joysticks? The TI joysticks are unreliable and hurt your hands. They used foam and mylar to make a connection that wears out and was pretty much flakey out of the gate. If you don't have the adapter and a good joystick that's probably most of your issue. Here's how to make one: http://www.mainbyte.com/ti99/hardware/cables/joystick.html I recommend the Wico Bat Handle joystick but everyone has their favorites.. The alpha lock issue blocks the UP movement on joysticks if alpha lock is on. Easy to fix, just turn it off. Or you can add a diode to your keyboard if you are good with a soldering iron. http://www.mainbyte.com/ti99/console/alpha_lock.html Greg Quote Link to comment Share on other sites More sharing options...
foxtrot Posted April 27, 2016 Author Share Posted April 27, 2016 Hi Greg, Thanks for the response. I currently have the wico adapter (and one other) and Atari compatible joysticks. It just seems that the joysticks aren't super responsive. Quote Link to comment Share on other sites More sharing options...

Doesn't help that TI didn't indicate ports though. Same with some of Commodore's machines, but at least with them, little harder to get tripped up I guess - due to the pinouts.

Do you have another machine to try? Greg Quote Link to comment Share on other sites More sharing options...
