When I was around 10 (1993-1994-ish), I remember watching a TV show where kids worked as secret agents, part of an organization called "Alpha Centauri" (or was it just Centauri?). I found their technology extremely fascinating at the time -- laptops, iPhone-like gadgets, secret headquarters hidden in a farm. I remember one episode that involved the Crown Jewels being stolen.
Does anybody remember the name of this show?
Edit: They'd usually sign off calls by saying "Centauri Out".
