Sorry for intruding(I was spying with Google Translator...), but it would be interesting someone with a Box-soft mouse would try the new previously unknown
driver, MOUSE.XR version 1.1.
As I've read in that mentioned thread, it seems the
interface is pure simplicity, but the mouse itself is a rare early NEC brand and was first adapted to C64 by a second party company. Its protocol has some resemblance, but incompatible, to the Commodore official who was the Atari, Amiga, etc, joystick port, and so it isn't serial as Mészáros's mouse card.
I have found one Neos Mouse in Amazon and will receive it on Wednesday, then I will compare inside the Amiga and Neos mouses...
