Only one request: Make sure it fits in an A2000 mouse port. The Punchinello (which converts M$ serial mice to Amiga) doesn't really fit unless you grind it down.
Also, I found one other problem with the Punchinello. It's rigid and sticks out the front of the 2000PT (Polish Tower aka A2000D turned on it's side) so far that if you walk by the 2000 too close you break it off.
A solution would be to have the Amiga mouse port connector on a cable instead of directly on the dongle.
