I've got a nasty one booting with today's current. Think I vaguely 
recall seeing it before, so sorry if this is known. I'm gathering this 
data using the pen 'n paper approach, so if its not exactly right, you 
knwo why:

[more stuff - losing the will to live at this stage]

Hope that helps somebody, shame i can't read my own writing.
