Collector Posted July 31, 2006 Share Posted July 31, 2006 (edited) I recently bought one of these with the game Parsec. The system works great, everything but the controller. I was able to gather that the controllers plugged into the left port, but do you have to do something in order for the system to recognize it? Both controllers do not work when I play the game and Parsec is pretty tough using the keyboard. Maybe my controller or controller port is faulty? I didn't know if there was some command starting up or during the game to change the game from keyboard control to controller.

Lemmi Posted July 31, 2006 Share Posted July 31, 2006 When you use joysticks on the TI-99/4A, make sure that the Caps Lock key is up. After the hardware was designed and already being manufactured, they realised that up won't register anything if the Caps Lock key is on.

JagFan422 Posted July 31, 2006 Share Posted July 31, 2006 i'm having the same problem with the one i just got. Bought some joysticks off Ebay on a whim, they were untested. I got them home and nothing. Nothing registers at all, the joysticks look in very good shape too, i wonder if its my unit. Quote Link to comment Share on other sites More sharing options...
Christophero Sly Posted July 31, 2006 Share Posted July 31, 2006 If it's not the Caps Lock key, then, unfortunately, it's probably the sticks themselves. Original TI sticks are the most unreliable sticks I've ever encountered. I've never found a working set. Quote Link to comment Share on other sites More sharing options...
SteveW Posted July 31, 2006 Share Posted July 31, 2006 Aw crud, it's been such a long time since i've fooled around with TI BASIC, I can't remember the proper commands. Otherwise i'd write a quick program you could type in to test your sticks. The Caps Lock thing is what people tend to get screwed up on. For some reason, up on the joystick can't register with the caps lock key pressed down. Your best bet would be to buy an adapter so you can use Atari compatible joysticks on your TI. A few different companies made them back in the day. Hopefully one won't be too hard to track down. Quote Link to comment Share on other sites More sharing options...
kenfused Posted July 31, 2006 Share Posted July 31, 2006 You can also build your own. Here is one link: http://www.mainbyte.com/ti99/hardware/cables/joystick.html I remember also seeing an article in Compute! magazine. Maybe the diodes can be eliminate if you only need one stick?

jsoper Posted August 1, 2006 Share Posted August 1, 2006 That mainbyte schematic had some mistakes, don't remember what they were offhand. Quote Link to comment Share on other sites More sharing options...
+remowilliams Posted August 1, 2006 Share Posted August 1, 2006 That mainbyte schematic had some mistakes, don't remember what they were offhand. Glad you mentioned that, I was going to build it and see what happened. I think that pic was the first schematic I've seen of the TI wiring.

Prodos8 Posted August 1, 2006 Share Posted August 1, 2006 If memory serves, this program will show values of -4 and 4 for each axis of the joystick (assuming they work) when pressed. It'll work using the standard console basic. Can't recall how to read the firebutton though??? 10 CALL CLEAR 20 CALL JOYST(1,X1,Y1) 25 CALL JOYST(2,X2,Y2) 30 IF X1<>0 THEN PRINT "X1=";X1 40 IF Y1<>0 THEN PRINT "Y1=";Y1 50 IF X2<>0 THEN PRINT "X2=";X2 60 IF Y2<>0 THEN PRINT "Y2=";Y2 70 GOTO 20 Quote Link to comment Share on other sites More sharing options...

Glad you mentioned that, I was going to build it and see what happened. I think that pic was the first schematic I've seen of the TI wiring. I had more time to look at it today, here are the corrections: TI pin 7 to Atari A pin 8, not 5 TI pin 2 to Atari B pin 8, not 5 Atari pins 6 to TI pin 4, not 6.

Original TI sticks are the most unreliable sticks I've ever encountered. I've never found a working set. They're not just unreliable... they're CRAPPY. Even when they do work, you'll wish they didn't. The sticks are very stiff and unweilding, and worst of all, they can't be replaced with other 9-pin controllers despite the fact that the system has a 9-pin joystick port. There are controller converters for the system, but it will take an immense effort to find them twenty years after Triton stopped manufacturing them!
