Okay, I tried the keyboard last night, it worked except for the left 'alt' and left 'Amiga' keys. :-(
I inspected the black plastic part that holds the key conductor things this morning, and remembered that the green part was actually glued to it. While ripping it off I think I damaged some of the tracks, probably the ones that lead to the left alt and Amiga keys.
On the A4000 K/B the '9(', 'oO', 'lL', '.>' (a straight line down the keyboard), mostly didn't work, and the neumeric '2' key sometimes didn't work, and the '3' (newmeric KP) key never worked.
I've decided that even though it will take a while to get used to the new broken(and working) keys, I'll stick with the newer(A500) green thing.
I'm now just wondering what the best way to repair the tracks would be. I would rather not use solder, since it would probably melt through the green thing.
(Note about the A500: The A500 that was the donor, was my first Amiga, and I left it with my brother for a few years, and just like every other thing he owned, he didn't know how to look after it, so it's dead, the space bar was stuffed(the plastic hooks that hold the metal leavers were broken), so now it's spare parts)
