Flight crew of a super MD80 failed to maintain runway heading as actually cleared due to not noticing amendment at the bottom of their ACARS clearance. Instead, they were following the SID departure instructions.

Narrative:
Early turn on departure. On departure started turn to 070 degrees at 3 mi as depicted on meade 1 SID. Upon contacting departure controller asked if we were flying runway heading. Replied we were turning as stated on SID. Departure controller told us clearance was runway heading as stated on clearance received from ACARS. We checked, and sure enough ACARS clearance was runway heading which was found at the very bottom. Lesson learned, read entire ACARS print out instead of assuming that today is the same as yesterday. Would like to see that any amendments to SID be printed right after clearance line instead of at the bottom.
