No need to disconnect the data and clock lines from the original controller.

Just do the solder work on the A500's keyboard to the assigned points on the A1200's board.

I think it would be better to avoid soldering (have one dead A1200 probably because of that).
better use the 'Lyra' system: get new socket, solder wires from A500 and then put socket on top of A1200 keyboard controller chip .
