Fix a 1200 keyboard with a 500 keyboard

[magistral]

Hi,

Recently i've bought a 1200 miggy via mercadolibre (third world ebay). Unfortunately, the keyboard have a lot of broken keys (the seller "forgot" that). Anyone knows how to fit a 500 keyboard into a 1200?. I know almost nothing about electronic, but i can learn.

Thanks in advance.

Well, the problem is: I think the matrix is broken... any tips?

Thanks.

@_yak_ : Can you please explain a little more?. Any pictures?.

btw: I've examined the matrix and cannot see any damages on it, but it doesn't work...

@Jope: There is any way to use any other conductive part of the matrix to fix the broken keys?. The keys Ctrl, White Amiga and Black Amiga are broken, so i cannot reset!

Thanks a lot.

The signals are the same?.
The data is encoded in the same way?.

Thanks a lot.

One more question about soldering...

I must solder it directly into the metal pins that are visible in the top side of the mother?
