I hope it's only

a small problem. The new board is working fine apart, it seems, from a couple of minor details. The power leds are supposed to reflect whether all the various voltages are working correctly. The twelve volt one does and the 3.3 volt does. The other two are not, however. This could be for any number of reasons so I will have to investigate thoroughly when I next get the time. Oh bother! (Or words to that effect!)
