Yep, the A1200 header gives you access to the main keyboard signals in parallel with the MPU. The signals themselves (clock, data and reset) are in the same places at pins 1, 2 and 3, but 5V and Ground are where the two LED signals are on the A500 so the power wires need to be taken care of. A very simple adaptor would be enough, but I would be wary of people ignoring the difference and launching straight in with A500-style connections.
