Amiga 1000 mouse not working

Hi, I did swap CIA's and no mouse improvement.  Will check with a joystick.

I just had a look at how the mouse signals are sent and it looks like there are two signals per axis, slightly out of phase to show direction.

I didn't think to examine both (all four) so I'll have to examine it again.

Oops just noticed I logged in with my old 8 bit username last time.. oops!

Didnt realize I had both names registered.

The port did work with a joystick so I ruled out the Amiga.

I had another look at the mouse and found that there was no PWM signal on the V/H/VD/HD pins.

I verified that the LED and optical sensors were working and concluded it was the quad comparator in the mouse that was bad.

I removed it and placed it in a breadboard and sure enough it's dead.

I have a replacement mouse on the way until i can finish the repair of the original.

thanks
