Well, I've made some progress. I'd already connected the battery but had no success, however, I tried again, and this time I was getting something back, and the little lights on the chip lit up when I pressed some keys, so that seems to be working. Bad news was, that when I hooked the HDD board up, nothing happened when I'd press CTRL-Z, other letters would appear, but it wouldn't being up F3>T. I'd press CTRL-Z, and all that appeared was a little arrow pointing to the right. I swapped the TX and RX connections, no difference. If I connected the PSU power supply to the board, I don't get anything appear on hyperterminal. Is there something in hyperterminal I need to change? I noticed there was a section on emulation, but I don't know what that should be set to, so I set it to auto. This is how I've set it up, and what I get: I'd placed a piece of paper between the exposed heads of the wires to prevent a short, I removed it for the pictures. And yes, that's a bus ticket I'm using to put between the PCB and the HDD case
