HELP - Testing TI99/4a Controllers

[Mr.Faxanadu]

Hello,

I have a set of TI99/4a Controllers that someone want's to buy off me. He want's to know if they work but I don't have a TI99/4a system. I tried to test them on an atari 2600 cause the ports are the same :embarrassed: Obviously this didn't work.

Any suggestions ?

Thanks

If you trust this person just give him the controllers and let him test them.

Use a multimeter.
