What particular sounds are you after? The squiggly leads, pads basses?
You have to realise that they're all fairly basic sounds as far as synthesis goes, often just sing basic waveforms with maybe a little filtering and the rest is how it's played and pitchbend or lfo to give the squiggly sound.
Any Synth can do the jist of the sounds but you're on the right track with the old school synths, Prophet(Main D-Train synth afaik and very distinct filters), Juno, Minimoog, OB-8, SH-101, DX7 etc
Cabrone is right, it's all in the playing - with the Arturia minimoog and Prophet you are basically covered - though D train also used the OBX .
I think it's all about the vocals - the boogie trax were all built around the vocal.
