Amiga 500 Keyboard Dead
 

Hi, i have amiga 500 keyboard with all keys are dead and put a new membrane but all the keys still do not work, I saw that the led and the rubber of the caps lock are missing, could this lack prevent the keyboard function?

It shouldn't stop it from working.

In your opinion what could be the problem?

Check the schematics: http://eab.abime.net/showpost.php?p=...1&postcount=15

Is the crystal working? Is the kbd controller power up reset working?

I don't know have a two kdb controller same problem....I will try to change with one kdb working.

Update 1: put a working kdb controller the problem remain the same,I am convinced that the caps lock rubber closes the circuit....it is impossible the all key pads to be damaged.

Update 2: i try the old membrane with kbd controller and a one plug rubber for testing, all the key pads results damaged this is absurd!

the caps lock rubber dosnt close the circuit unless you press the caps lock key.

:great
