Hello there. First of all, since this is my first post, I'd like to present myself. I'm from Portugal, I'm 27 and I like to collect everything computer-related that reminds me of my old times. I keep most of the parts that went through my PC and I'm actually still looking for the exact same model of Spectrum I had several years ago!

But, getting on-topic, I'm about to put my hands on an A500 (the same model I used to play on a friend's house when the Spectrum I had was starting to show its age). So, I dug out an A2000 a friend offered me a couple of years ago and I was experimenting with a serial cable in order to transfer some ADF files back to disk. Trouble is, after that experiment of mine, the mouse (using the other port) stopped working. I mean, not totally: the buttons still respond, since when I click them, the top window changes colour, but when I move it, the cursor never leaves the top left corner of the screen.
Did I screw up something for good? I don't know anything about the Amiga hardware, so any help would be appreciated!
Cheers!
