Funny you should mention that Jim... it happens that both of my 9W adapters
are now dead for no apparent reason, and I've been meaning to take my Dremel
to one of them and see what makes it tick.
In other news, anyone want to sell me a working Newton AC adapter? I don't
care if it's an old one or a 9W one, I'm down to one and would like to have
one at work and one at home.
