Rajada Posted September 2, 2015 Share Posted September 2, 2015 (edited) Hello, I'm hoping this is the right section because I found this little interesting thing that I think is for TI computers, and I'd like a little info on it. Here's a picture... I am under the impression that this is an adapter for TI computers, and looking for a little backup on that. From what I can tell, it looks like all it does is pull some pins from each controller and route them to other pins in a different, combined configuration. Not owning a TI computer, I'm not sure it has any use to me. I might sell it, but with something this old and dirty who knows if it works. I'd appreciate any info on this thing so I can make a more educated decision, and I'd really like to know if there's any way to safely test this thing, see if it's still working. I had a thought to test it on an Atari 2600, but I wouldn't want to risk shorting anything unless I was certain it would be harmless.

+jedimatt42 Posted September 2, 2015 Share Posted September 2, 2015 If you google these words, ti atari joystick adapter You'll find a schematic, and can test it with a continuity meter. It should allow connecting 2 2600 type joysticks to the TI's single dual joystick port. It will do nothing useful connected to a 2600. 1 Quote Link to comment Share on other sites More sharing options...
Rajada Posted September 2, 2015 Author Share Posted September 2, 2015 Nothing useful, or nothing at all? With a proper pinout of an Atari 2600 joystick port I thought I could at least verify continuity by observing effects on games. As long as it wouldn't short my system of course. I'm just not sure my multimeter probes will fit in those tiny recessed holes. Quote Link to comment Share on other sites More sharing options...
+Schmitzi Posted September 2, 2015 Share Posted September 2, 2015 Hi, I think it is for connecting the Atari-Joysticks to the TI-99/4 and 4A, but not vice versa. Quote Link to comment Share on other sites More sharing options...
Rajada Posted September 2, 2015 Author Share Posted September 2, 2015 Well it turns out I had some leftover 9pin connectors from fixing my paddle controllers and building an Omega Race adapter, so I plugged those in and used them as contact points. That was far easier, and I got readings on all the proper pins. So now that I know this thing is working, I guess I just have to decide what to do with it. If it was busted I was going to use it for parts, but it would seem a shame to waste it after I read about how god-awful those TI controllers were. 1 Quote Link to comment Share on other sites More sharing options...
Rajada Posted September 4, 2015 Author Share Posted September 4, 2015 Well, just to let anyone who stumbles on this topic know, I sold this device. Just hoping they get to use it, it certainly wasn't doing anything over here. 1 Quote Link to comment Share on other sites More sharing options...
Opry99er Posted September 7, 2015 Share Posted September 7, 2015 Good to know it went to a good home. These are very good adapters. Quote Link to comment Share on other sites More sharing options...
