Just look up different synths at http://www.vintagesynth.com as they have included the bands that used them at the bottom.

For 1979-81, Look up: Jupiter 4, Promars, minikorg, Prophet 5, OB-X, moog source, Pro-One, Juno-6, CS-15. Those were very popular.

And play everything through a Roland JC120 for that vintage british sound. heh.
