Hi Liam Great, if you did have the latest version that would be cool - actually if you did have a board still spare I would be happy to give you a couple of quid to post it to me, as it would be a quick way to learn a few useful physical things about the DIN connector footprint...!

Re: Formatting SD/CF cards for use on RISC OS 3.1

PowerIDE uses the native IDE interface in the A3020 etc, I don't think it'd work with this :/ d.
