|  Re: Joystick/Pad recommendations
I wouldn't try anything with built-in logic.
The problem is that Atari/C64/Amiga style DB9 joystick connector has a ground and +5V connections. On the plus/4 we also have a select line. The simple adapters just connect select to the ground of the DB9 part thus leaving +5V always connected and GND floating when select is not active. This causes random impulses in most of the joysticks which in turn destroy TED.
I've been thinking about an adapter with a simple logic where ground and +5V is always connected and directions+fire is masked (OR-ed) with select. I don't know if it would work or it would pull up all the lines and thus making keyboard operation impossible.
