An addition for your Amiga Connections wiki page:

On an Amiga 1000, CSYNC is found at pin 12 of U6A.

The RGB signal is connected to either R25 (red), R24 (green), or R23 (blue). On my machine (a NTSC machine that was converted to PAL), there are two resistors in series for each color channel. I connected the signal between the resistors. If there is only one resistor per channel, a separate resistor is needed (untested).

On the attached photos, you can see the CSYNC signal (brown wire) and RGB signal (yellow wire).

I haven't added the keyboard option, but it should be sufficient to add the wires to R50 (KB_CLOCK) and R51 (KB_DATA). Care should be taken: These are pull-up resistors, one end is connected to +5V. The wires need to be connected to the other ends, respectively. (Untested)
