Atari joystick 9 pin tester ? homemade

Recommended Posts

Got this in a lot of old Atari repair stuff. Made out of an Atari power supply case. Used to test pins current ? Your thoughts ? How to hook it up ?

that is interesting.  It seems made to pug into a console (female end).  Can you open it and see what kind of circut is inside?  I would probably look for continuity pin to pin and expect each pin to connect to 8 at some knob rotation.  I cant imagine its use though.

Without seeing the inside, my money is on port pin tester.  Would work with Paul's Testcart nicely.

 

From the looks of it, the switch has 6 positions and position '8' is GND, when you select any of the other pin numbers, they will be switched from floating to GND, indicating to the port, that the button was pressed.  Why they would only ground one of the paddle lines is beyond my guess.

I think CPUWIZ may be correct in suggesting a port pin tester.

I would assume that it is a rotary switch (12 to 1 with some positions unused), it makes sense for 7 to be missing as you do not want to short the supply. I can see that they may want to connect pin 8 as an "no input" condition, but if a 12 position switch was used it would have made more sense to connect to pin 9 instead and simply turn it to an unused switch position (i.e. between 4 & 5, 5 & 6 or 6 & 8 ) for no input conditions instead.
