RJ12 connectors arrived and so have tested 5V and GND were showing on the right locations on the adapter. Looks like TX and RX are wired correctly as well.
CKBD adapter with my Mega ST is now tested and USB devices work. Dell Keyboard and Microsoft Basic mouse both work fine. :)

Moving on from my initial CKBD adapter for my Mega ST which is effectively an Eiffel adapter without the PIC chip. It was time to integrate the new CH559 chip onto the PCB.

Apart from getting the TX and RX connected the wrong way round, it works. :D
All ports tested and working. Ended up with wireless keyboard and mouse connected to the USB ports on my Mega ST.

I think I now have my Mega ST CKBD adapter where I want it.
USB wireless keyboard
USB wireless mouse
UniJoysticle2 Bluetooth joystick with my Xbox controller connected
Totally wireless connectivity - no wires getting in the way.
Here is the final adapter
