Aye, the same circuit. As I say, its a bit difficult to get hold of, hence the DIY approach...
The circuit layout is largely the same. A few bits are in exactly the same place, but I've tried to keep it close.
No pics yet, I haven't had the board made (need money). But (if and) when I get them done, I'll be happy to post pics of a blank board and a populated board for your delight.
