I hope this is not too far off topic.
Do track-balls still exist for the Amiga?
I have several of the Logitech Marble Mouse (Yes, it really is a trackball. Poorly named.) with USB interface. It goes thru a USB-to-PS/2 adapter and then thru a Cocolino into my Amigas, plug-n-play (no software or drivers required). It has the tactile spring-leaf contacts. These work great. I now like them better than any mouse.
I believe these were originally available with a true PS/2 interface. Then they sold them as USB with the adapter included. Perhaps they still use an older PS/2 protocal?
I have USB Kensington Orbits to use with Macs and PCs. I'm not sure they work thru the adapters with Amigas. I'll have to try it.
