Subject: AMX mouse wiring

I'm trying to connect an Amiga mouse to the BBC userport as per instructions 
found on various web sites.
Problem is, it doesn't work quite right. The mouse X direction *only* goes 
up, and the Y direction is reversed from what it should be.
Here's the pinout I have:

BBC USER PORT      name      AMIGA    name
Pin 1                          +5V           Pin 7        +5V
Pin 3                           0V            Pin 8          0V
Pin 11                         X-Axis      Pin 4      Mouse HQuad
Pin 12                         Y-Axis      Pin 3      Mouse VQuad
Pin 13                         X-Dir        Pin 2      Mouse H
Pin 14                         Y-Dir        Pin 1      Mouse V
Pin 18                         L-Button   Pin 6      Button 1
Pin 19                         M-Button  Pin 5      Button 2
Pin 20                         R-Button   Pin 9      Button 3

Can anyone see a problem, or have a different configuration?
