    A little rant

    So courtesy of a failed firmware flash we need to access some debugging pins on a bit of hardware here. Initial prognosis was that it's a dual in line 60 way connector - two rows of 30 pins, 2mm pin spacing. Unusual, but not that odd - laptop ATA drives are 2mm spacing for example.

    However, have now just realised that while the row spacing is 2mm, the "column" pitch is 0.1" (2.54mm) which makes it a very odd animal indeed. Thankfully we only need two signals plus ground off this puppy so can stick some wires in to get at them, but, sheesh, why mix standards!

    Ok, I'm better now, thanks for listening.
