looks like a nice bike, I had one in the team colours from 1984, sort of brown/bronze coloured main triangle tubes and polished aluminium forks, head tube and seat and chainstays.
they are a great ride, quite flexible if you are a powerful rider, but then if Saint Sean can ride one anyone can!
have a look at this link: -http://cyclespeugeot.com/index.html
and go to the catalogues page, I think your bike will be listed in the 1984 UK.pdf catalogue as a PX10DU '979'. The original equipment is listed there.
as a newbie, and having paid only £40 for an excellent frame, you might be a little scared by the prices of Campagnolo Record or Super Record parts to match the pro bikes!
is the top tube cable entry port a little "frilly" round the edge? I have found that a problem caused by running the cables under the handlebar tape, I solved it by taking the cables out the top of the levers, 1970s style.
have a search online for Robert Millar and Peugeot, he rode one of these very successfully.
my current Vitus is a black mid 80s 979 with a steel fork, badged by Partingtons, a bike shop in Bolton I gather. she's my winter bike with a real mix of parts.
all the gear and no idea it's not still 1989......
