How to identify this older Peugeot road bike?

How can I identify this bike? I rescued it out of somebody's trash on
garbage day, and it appears to be a pretty nice road bike (I was expecting
a dime-a-dozen 1980s 10-speed).

I can take detailed pictures with my digital camera if anybody thinks it
would help.

Keeping in mind that some components have probably been changed, here's
everything I can list about it:

"Peugeot" in blue letters over dark grey dithered fading-towards-rear
checker-patterned boxes on top tube
Dull silver or metallic grey general paint color
Chrome-plated/polished fork
"Super Vitus 980" "Special Double Butted" tubing
Major tubing joints have reinforcement metal on them, looks almost like the
sort of tubing connector where you slide all involved tubes into it; but it
is obiously only a reinforcement due to it's thin gauge.
Mavic Module E2 rim on rear
Rigida 7000 rim on front, slightly wider; I suspect this rim was original
equipment for both
Peugeot Helico Matic rear hub, no label on front hub Mostly Peugeot
components (drivetrain, brakes)
Quick-release hubs
"Laprade" seatpost which appears to be cast-aluminum
Selle Italia RS saddle
Large chainring has very fine logo printed, may say "Strongught" or
something similar
(I just looked with a magnifying glass, looks like "Stronglight")
Downtube shifters; they have "S" stamped on face near the end
"Mafac" stamped on brake levers (single-type/aero levers)
1926363, PF60, and 56 printed on a label on the underside of the bottom
bracket
3 chainring, 5 cog
Large round reflectors on front and back
Found with old 700c x 25 x 90psi Michelins
threaded-style stem
Brakes each have a single cable that ends in a bracket which then has a
seperate short cable whose ends attach to each side of brake (is this a
"double pull" brake?)

Thank you,
