It's the same as with serial ports on a PC: They have the same physical connector, but it's a different protocol and different voltages. There's the danger of breaking the device, the computer's port, or even both.
This is a good time to pose the following question then.
While we know that the Megadrive/Genesis gamepads don't stricly adhere to the Commodore/Atari specs, and that there's a stray pin which works only by pure chance (SELECT I think?), is there really a danger for the Amigas? I mean, a real
chance of damage, not something which could happen only in 1% of cases
I've seen loads of people use them for ages on their Amigas with no issues at all and I use one myself on all my Amigas without any issues at all... While I know that there's real danger when using them with a C64 because of something different in the pinout (can't remember now).
Thanks for your time, Jens!
