This picture shows the French/Belgian version of the A1000 keyboard. Keys such as RETURN and TAB have symbols printed on them unlike the US version which used words. This keyboard also has additional keys which the US and UK versions don't for additional characters.

The A1000 uses an RJ11 style keyboard connector.
Please note, I've heard differing accounts of the pin signals for the A1000 keyboards. Some reports say that Pin 4 is +5V and Pin 1 is GND.
