Keys Mutated

A mere continuation of the previous post. This had to wait for many days since i was a bit occupied with the work at hand. Here goes the layout of the part of keyboard that is not working.

|Esc|
|~||!|
|Tab ||Q|
|Caps||A|
|Shift||Z|
|Ctrl||Start||Alt|

And interstingly, here is the outcome of certain experiments done on this part. Under normal circumstances, "Caps" works fine. Here goes the crazy output of experiments.

First Attempt: (Assuming Caps is off initially)
 Caps + Tab + Q = W
 Caps + Tab + A = S
 Caps + Tab + Z = X

Second Attempt:
 Caps + Tab + Q = w
 Caps + Tab + A = S
 Caps + Tab + Z = x

The above shows some kind of shift in the circuit. Another experiment with surprising results, generally when the keypad works normal, and we press two keys at a time, one which has got the connect first (ofcourse we couldnot press two keys in sync.) would be printed or one/two characters would be printed and it stops there. But the three keys, 'Q', 'A' and 'S' behave differently.

Assuming Caps lock is off initially,

Caps + Tab + Q + A + Z = WsXwsxWsXwsxWsXwsxWsXwsx

Oh! What has happened? 'A' has got some real trouble and there is a short as expected before in the keyboard circuitry and so that it connects 'S' with 'A'.

No idea, will be debugging this issue i guess this end of week.
