OK, I'm staring at my recently acquired HP Portable Plus with it's oddball
power plug. The FAQ tells me it wants 6V, but the only thing I have that
fits is an 8V supply from a 9114, which I'm sure will do the trick, but I
don't see two things: a polarity key and a power switch. Does the Plus
care about polarity? If not, how do I turn it on?
