The only mention about 21066A is as "future DECchip 21066/21068 processor upgrades" Interesting about your version is that they also mention a 21068A. Wonder what's different between 21066 and 21068 beside the clock frequency that they gave them a different number. Considered that it made it into A revision there must have been a market for it. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
