The Rev2's 4 pole filter would be able to recreate the sound your after no problem.
I doubt it would of been an sh101 as that sounds very polyphonic to me.
There's no reason why a DX7 couldn't of been used, it was very capable of creating analogue sounding tones and not just bells and electronic pianos.
If your trying to create it, both synths in your armoury would be more than capable.
