Hmm, you could well have a point there. There's around 150 ICs of LS-
logic complexity on the board, then around 30 or so more complex

If I can work out which pins on the euroconnectors provide power then
maybe I should hook a known-good 5V supply up to it and see if that's
happy powering things...

10 ohms means about 0.5 amps -- sounds like a perfectly respectable
amount of current for a board with "lots of silicon" to draw.
So... are you sure there is a short, rather than just circuitry?
