It's working! 2 dud LEDs in the matrix was causing the CS to misinterpret button presses. Didn't realise they were dud for ages.

@jayteeIt was still dropping the 5v to 1v, but eventually I fixed the problem. I am not entirely sure where it was as I went through a very long process of checking for shorts and reseating ICs. Anyway, it's working now, I have sound from my two SIDs, information on my screen and lights on my control surface. Now to sort out the buttons that still aren't working, so will return to my CS troubleshooting on the other thread. Thanks @jayteeand @Hawkeyefor you help with this one. It was a total pain but I have come out the other side with a better understanding of how this machine works thanks to your advice.
