Help with 'old-school' Tangerine Dream sound???

If anyone could guide me in the right direction for obtaining (or approximating) within PT the following Tangerine Dream sound, that would be wonderful. The TD sound is from their 'Thief' soundtrack (circa 1981) and kicks in within the following link at approximately 2 minutes and 10 seconds into the track. It's hard to miss.
