What synths were used in Hold that sucker down by the OT Quartet

If you're not referring to brand names, maybe you can determine that
By listening to them?

Might help if you look for Rollo Armstrong's instruments as he is OT Quartet (it was just an alias for that track)

I have a great patch for Sylenth 1 that sounds very like one of the synths on Hold That Sucker. There's also some great presets on the Korg M1 that sound like stuff Rollo made.
