My idea of truly classic techno :

Mills - Step to Enchantment
Slater - In from the Night / Moave Violin
Mayday - Icon / It is what it is
Model 500 - Nightdrive thru Babylon / Into Battle
Claude Young - Nocturnal / Planet Earth
Aphex Twin - Joyrex 9 / Blue Indicator
FUSE - Substance Abuse
Mover - Frontal Sickness
Mescalinum United - We have Arrived
Advent - Badboy
Beltram - Energy Flash
3 Phase - Der Klang De Familie

Probably plenty more...
