@ doctorq - thanks for the link. A second drive on the internal connector would be a really neat solution (and all I need really) and I'm now wondering if a DIY hack can be done based on the one in the link. I'll investigate further.....
I think you need the chip that's on the PCB board, but I don't know for sure. You can also take the easy solution and make me an offer on it :-D You have already seen a picture of it.
