Re: I found it! A very sorry looking MK14.
Hmm, actually, you only get a single 'O' (or with the old OS, '-') if the system is held in reset after it has been running correctly, since the segment output hardware remembers the last character which was sent to it.
Edit: Just caught your response. Sorry to have to ask, but you've checked the +5V rail is spot-on volts wise?
