Kempston Mouse driver

[oblo]

I will try later. Using Kempston joystick should be pretty strightforward. A simple function could be done IMHO with few INs intructions. Do we really need a "driver" :?: Perhaps this routine adds more high-level logic?

It's not Kempston Joystick, it's Kempston Mouse ;-) And yes, Kempston can be read using only INs but Chri's driver adds a pointer that works pretty good. You can see later when you try the PoC :-)

Cheers
