Unfortunately, a solder pad where I had connected the wires for the serial port ripped off. I googled how to get around this and apparently the way to do so is to lightly scratch off some of the top layer of the circuit board to get access to the copper connector underneath. I re-soldered and thought I was out of the water. however when I connected back up to the PC I realised although I could see the data in the shell passing, I realised the shell wasn't accepting any keyboard inputs.

Any recommendations how to salvage?

You can try taking the pcb off and test pads on the back of the pcb, there might be 2 points works the same as serial debug on the other side which you have ripped off...at least on KT2 this method works perfectly

@eddie.t.h, thanks. I have now soldered the connections however when I plug into my CPU I get no readout on the terminal as I cannot turn it on. This is the same even once I have installed the new battery

And the computer somehow detects it? For example, as a NS Blank CODEX?
Try using kubrick and see if something appears on the terminal. In this model, Flash memories were often damaged. If this is the case, you will see a message about the lack of serial numbers.
