We can rebuild it. We have the technology. We can make it better than it was. Better, stronger, faster....Tezz wrote: ↑Sat May 27, 2017 8:17 pm Thanks Mark, that's a shame that they turned out to be poorly implemented Kempston interfaces I was going to take a look into the other interface to see where that disconnected black wire came from thanks for that, I guess that along with the other issues you noticed is the reason why that one has a label taped to the back with "U/S" on it With that important design flaw I don't suppose these interfaces will be much good to anyone.
