Please note, for the CPC6128 you use 16-bit addressing mode, and these modifications are unnecessary.
=== PCW Expansion port adapter video circuit fix ===
Due to an error in the schematic capture, the video circuit on the PCW Expansion port adapter isn't actually connected to the PCW. The fix is straightforward and involves putting in a couple of jumper wires as follows:
* Connect Expansion port connector Pin 44 to U1 pin 1
* Connect Expansion port connector Pin 46 to U1 pin 4
If you use copper wire such as you find on a transformer or prototyping wire, you can connect these pads before assembling the expansion port connector and U1's socket. It's best to lay these on the underside of the board:

And once fixed, the video circuit works nicely, giving a good clean signal:

You may find it necessary to adjust the trimmer to get a signal. When assembling, set the trimmer about half way to begin with, then adjust it in situ until the best picture is obtained. Don't forget, you're going to need to make up a suitable video cable, too. The composite video signal is on the pad closest to the trimmer, with the ground pin next to it. This is marked on the board in tiny letting.
